RELATIVE stopping power, one-shot-stop

Status
Not open for further replies.
All the studies are "worthless" in one sense, the time spent reading, analyzing, debating , testing etc., would be better spent learning to shoot accurately on demand under any conditions with whatever "banger" you happen to have.

OO buckshot? Jim Cirillo shot a guy dead center in the chest at a rooms length distance. The "shooteee" ran away and was gunned down with multiple .38s and soft point M-1 carbine rounds. Jim has said, in a public forum, that OO buck is worthless. he allowed that slugs worked "most times". (If you are not familiar with Jim and his official count of 19 dead "perps"(he killed more) look him up.
 
10mm has the best one shot stop statistics as an semiauto round. The .45ACP follows close behind.
 
Well, when I was working in the hospital as a kid, paying off my second motorcycle with a $1.45 an hour night janitor job, a guy walkked into the emergency room holding his guts in his hands. He'd been shot up close with a 12 gauge in the abdomin and he drove himself to the hospital.

Odd things happen, poor shot placement in that case, but at any range, a 12 gauge is nothing more than 12 .31 caliber balls from a pocket Remington. That's about the power of a .22 long rifle in each pellet. Unless you're pretty close, you might NOT kill the guy you're shooting at. He certainly won't vaporize like some people think of a shotgun.

Has nothing much to do with M/S data, however, just that I agree the shotgun is highly over-rated with buck.
 
Michael, while your preparing your paper, would you mind providing some actual documentation that the Stausborg tests ever actually occured?

Historians and lawyers are concerned with documenation. Scientific validity only depends on a sufficiently adaquate description of the experimental method to allow the results to be replicated by independent parties. This is available for the Strasbourg tests.

Given the level of agreement that the Strasbourg tests have with a number of pressure-wave related live animal experiments already published in the peer-reviewed journals, as well as our own live animal experiments which are in preparation for publication, I'd say that the burden for documentation is squarely on the shoulders of those who suggest that Strasbourg was a fraud.

Calling for documentation is a red herring. If Strasbourg were a fraud, it would be easy to disprove: shooting a number of goats with the same loads under the same conditions would produces significantly different average incapacitation times. You wouldn't have to use all the different loads as the original tests: showing significantly different average incapacitation times for a small number of loads would be quite sufficient to prove Strasbourg a fraud.

So here we are, 15 years after the first suggestions that Strasbourg was a fraud, and no one has proven the accusation either with evidence (documentation) of fraud or by a failed attempt to reproduce the average incapacitation times. Yet over that same 15 year time period, the evidence supporting the Strasbourg finding that a pressure wave plays an important role in incapacitation and neural injury has been steadily increasing.

If you summarize a specific statistical analysis in your own words (showing at least that you understand it) and give a reference, then I will be happy to comment on the validity of the analysis and the conclusions.

Our research group has considered all of the published criticisms of the M&S work of which we are aware, and none of them is sufficient to conclude that the work is fraudulent or flawed to the degree you assert.
You didn't answer my question. Why do you disagree with MacPherson's analysis?
Summarize the criticism you are referring to and give a reference.

Also in preparation for publication is a paper, by me, that further documents the difficulties in obtaining valid shooting data.

Edited to add:
There are disagreements as to what is a one-shot stop, and what isn't. For example, in the last M&S book, "Stopping Power," the .32 ACP "single mother" anecdote on pp. 242-243 does not appear to be a one-shot stop, as the bad guy was able to continue hostile activity after he was shot. Then there are anecdotes in which there are no witnesses to the bad guy's immediate reaction to being shot, for example: pp. 252-253 (Trooper/AR-15); p. 265 ("Federal .357 SIG 125-grain Failure").

But the Strasbourg tests also find excellent correlation with the M&S data set, and these have been published for some time.
It will be interesting to see how your research is received/accepted, and by whom.

Folks pistols are not death rays. If you want one shot stopping power drag a cannon around with you. Handgun cartridges are pretty anemic at the best of times, better than rocks, great for defense if you don't have a shotgun or rifle or better yet a good pair of runings shoes. My .45acp and 9MM rounds won't go through 6 feet of snow if you are into shooting snowmen. Nor will a .44 mag. out of a handgun.

Like somebody said a bullet in the head no matter the caliber ends the fight, so too a hit in the spinal cord.

You only die from two conditions, trumatic damage to the nervous system or blood loss. If you want somebody to fall down shoot them in the groin and break the hip/pelvis, if you want them to die quickly hit their head.

Personally, if given a choice, I like a good pair of running shoes.:)

oh, and while you are at it...

..please provide proof that the Holocaust happened :rolleyes:

Sheesh. If you can't disprove it, just deny it.

Good thing we have a signed copy of the Declaration of Independence or some people would say the Revolutionary War never happened either.

Pass the tinfoil, please.
 
Revolutionary War?!

so that explains all the recent immigration from N.Y recently...here I thought they were coming for the beer. LOL

Sheesh. If you can't disprove it, just deny it.
Where are all the data (strip chart recordings, video of goat reactions to being shot, etc.)?

The only "proof" that The Strasbourg Tests occurred is a preliminary report that was anonymously "leaked" to influential gunwriters at a time when there was great controversy about handgun ammunition performance and selection. Question those who allegedly "are in the know" about Strasbourg, and one will tell you it was a secret government test, whilst another will tell you it was private reasearch.

Consider nonsense like this alleged "Strasbourg Tests" phone call transcript, posted by somebody who suggests that he's "in the know:"
"Hello, is this Dr. ______ (Deleted)? Comment deleted at called party's request. I received a call from a mutual acquaintance a few days ago and he thought that it may be beneficial if you and I spoke regarding the results of the Strasbourg Tests. Comment deleted. He asked me not to say. Comment deleted. Because it might affect your working relationship. Comment deleted. I'm not at liberty to divulge my identity, but he's under the impression that you may have questions regarding the legitimacy of the tests.....and maybe I can supply you with some usable information. Do you have time for a brief discussion of this? Comment deleted. Good. If you'd like me to proceed with this conversation, I'm required to inform you that you are on speaker phone and that both sides of this conversation are being transcribed. This transcript will be turned over to my superiors as well as to the editor of a law enforcement publication. This conversation is not being electronically recorded, but if you'd like to tape record your end of the conversation, feel free to do so. Please bear in mind that by regulation I am required to make it clear that I am not giving you permission to record my voice. A transcript of this conversation can be supplied if you would like one sent to you. Comment deleted. We can have it to you in twenty-four hours. Do you have any questions or objections regarding the required procedure I just outlined? Comment deleted. The entire transcript must be turned over to my associates but we can edit out your comments if you insist. Comment deleted. That's right, your comments will not be published. Would you like to proceed under these conditions? Comment deleted. We have your permission to proceed, then? Comment deleted.
To start, I'd like to make you aware that these tests really represent an unprecedented merging of military and trusted, private sector personnel and funding.....and while these tests were organized and directed by both retired and active military personnel, they were not directly sanctioned or funded by any branch of the U.S. military. Did you happen to see the 60 Minutes interview with Dr. Carey several weeks ago? Comment deleted. If you had, you would have sensed the pressure which was applied to his research team by animal rights activists and you would easily understand how apprehensive our entire military is regarding any further accusations that they are guilty of what the activist groups interpret to be the unconscionable killing of hundreds of helpless animals. Are you familiar with Dr. Carey's experiments? Comment deleted. Well, Dr. Carey is a military surgeon who was conducting experiments that entailed firing B-Bs into the craniums of anesthetized cats in an effort to identify the brain chemicals responsible for blood clotting in brain-shot soldiers. The bottom line is that even though these tests could help in saving the lives of wounded soldiers, the animal rights groups couldn't have cared less and effectively shut him down and gave the military a black eye in the process. Dr. Carey and his wife are still receiving death threats because of his experiments. Even though this.....save-the-animals-and-kill-the-humans type of mentality is twisted, it nonetheless prevails and is gaining momentum in this country. Unfortunately, the press bends over backwards to give these groups their full support. Comment deleted. No, a Naval surgeon.

With this said, I should mention that several of the members of the team are still active, high-ranking military personnel who are very concerned about being caught in the cross-fire of activist character assassinations and severe military discipline which could cost them their pensions. It's for these reasons that the Strasbourg researchers are so adamant about maintaining their anonymity. Comment deleted. I'm glad you can appreciate their concern..... could you tell me why you won't allow your remarks to be printed.....I've assured you that your identity will be protected? Comment deleted. Even if they did determine who you were from the context of your remarks, I'd think your colleagues would understand that you're just defending their position. Comment deleted. But your branch is so far removed from the melee. Comment deleted.

Well, your decision has been duly noted.....I can give you a little background on the research group if you have time? Comment deleted. One thing that should be emphasized is that the results of these tests were never intended to be distributed to the general public. The fact that they've become public knowledge by way of a recent magazine article might leave key people within the ballistic community with the impression that they were. Actually, the test results were meant to be released only to sponsors and upper-echelon military brass who were in turn going to share the information with federal agencies. To make a long story short, a leak occurred, which is, as you know, an inevitable consequence whenever the honor system is employed. The leak sprang from within a federal law enforcement agency and from there spread to major police agencies and eventually found its way to the shooting journals. Comment deleted. That's correct. Well, all this created major problems for the Research group. Aside from the threat of crucifixion from animal rights organizations the group was very concerned about having incomplete data released.....the data I'm referring to encompasses figures recovered from strip charts.....EEG and transducer charts which were not part of the preliminary report. Another major concern was that the particular agent responsible for the leak might have access to videos or photos showing these animals floundering around after being shot.....definitely not something they'd want the A.S.P.C.A. or Friends of Animals to witness. Unfortunately, this particular concern proved to be a legitimate one, as they've recently gotten word that at least two of these videos and possibly some photos are, in fact, in circulation within at least two major U.S. police departments. So, while they can't do anything about this security breach, they are attempting to minimize premature assumptions and misinformation stemming from the release of preliminary data by attempting to make complete and accurate information available to major police departments. This is taking the form of direct contact with some of those departments as well as letters and articles in police journals and other magazines. Comment deleted. How else could it safely be done? Comment deleted. They have to be selective.....this isn't something that can be sent to People Magazine.....the point is it's an effective method.
Previously, the credibility of the tests was never even an issue with members of the Strasbourg group since the full report to the military included all the chart data and over 600 photos and video tapes of the shootings. But now, because they're getting reports that there are some influential people out there who are questioning the genuineness of the tests, they've become very concerned.....primarily because if police departments dismiss the tests as bogus, they can and will make wrong decisions by selecting inferior ammunition that over penetrates.

From your viewpoint, what would serve as proof that these tests were authentic? Would a couple of videos or strobe photos qualify as proof? Comment deleted. Well, for what it's worth, I have the feeling that some ill-gotten evidence is bound to surface in the near future.....simply due to the fact that if a federal agency can't prevent a leak, there's no reason to believe that police departments will fare any better. Comment deleted. You're exactly right, the root of the problem is misplaced trust. The.....camaraderie that exists in the government agencies and police departments engenders trust. The next thing you have is an agent or officer divulging every detail to his or her brother-in-law.....and then classified information finds its way to the New York Times or 60 Minutes.

How much information do you have regarding the Strasbourg Tests? Comment deleted. Could you tell me how you obtained this material? Comment deleted. Don't be, I understand about protecting sources.
Do you think you can fairly assess the tests without studying all the data? Comment deleted.

From my point of view, you and several others are in a position to aid or harm this study. If you'd like, I can submit your name to the group leaders to see if they'll consider sending you a complete report. Comment deleted. If the request is approved, probably within a week.

If you'll allow me to backtrack a bit, I mentioned assumptions earlier.....ironically, the same assumption was recently made by members of the two opposing camps. Evan Marshall and Martin Fackler both erroneously assumed that these tests were conducted in Strasbourg, France. In fact, it's my understanding that Mr. Fackler made a special trip to Strasbourg, France in an effort to substantiate these tests. Our sources told us that since he found no proof of a test facility there, he again erroneously assumed that the tests never occurred.....what a coincidence.....he wasn't involved in coordinating the tests, or invited to participate, so he declares them fallacious. This is like you and I traveling to St. Louis and interviewing all the people in the city named Strasbourg to see if they were involved in goat experiments.....and after finding no one with test facilities in their basements, assuming that the tests never occurred. We obviously erred in our approach. We should have taken into consideration the fact that there are hundreds of other cities containing people named Strasbourg. My point is, there isn't any room for assumptions in investigative work.....or ballistics.....especially when such a gargantuan assumption can cost police officers there lives.

Comment deleted. Well, that's something you'd have to tell me, I'm not assuming that you made the same assumption, I'm only relaying what someone told me.....that you have reservations. Comment deleted. I'm glad to hear that.....I wish everybody was as open-minded.

Are you aware that the funding for these tests was provided by donations from private sector and military sponsors? Comment deleted. Well, I'm one of those sponsors and I can tell you that the tests occurred here in the states, and that I have personally visited the test facility during testing. Incidentally, the difference between the preliminary report you have and the report I have is.....mine cost five thousand dollars. Besides being personally known by one of the members of the research group, that was the minimum donation required to become a sponsor. A lot of dedicated people invested hard-earned money to learn the outcome of these tests.....and a good many of them aren't happy that these tests have become public knowledge. But that's water over the dam.

Another thing that should be made clear is that the members of the research group aren't claiming that these tests reflect the final word on the subject of incapacitation.....but they do claim that they provide a very close approximation of what will happen on the street when an unobstructed lung hit is involved. Since the scientific approach they used has determined that incapacitation is system pressure related, certainly ammunition rankings could be altered if an anatomical obstruction was involved, such as the humerus or even the triceps or biceps muscle. It appears obvious to me that obstructions account for the intermittent disparity between the ammunition rankings of Fairburn and Marshall as opposed to Strasbourg. Obviously, many more variables are involved in street shootings.....for instance, the angles of impact are rarely the same.....and the fact that other organs are involved makes a great difference in the outcome. That's why the tight controls used in the Strasbourg tests are so valuable.....five subjects could easily prove to be a more valid indicator of stopping power than twenty five or thirty street shootings. Comment deleted. Yes, statistically that's extremely important. Without such tight controls, the tests would be essentially worthless.

Since we're on the subject, another thing I feel is important is the way the researchers procured the ammunition used in the tests. All this ammunition was purchased off-the-shelf, through various retail and wholesale establishments with Strasbourg funds. To maintain tight security, none of the manufacturers even knew their products were being tested. After testing was completed, the manufacturers then received a report. This approach prevented any special ammunition from skewing the test results.

My main concern.....now that the Strasbourg study has become public knowledge is that law enforcement officers at every level are going to suffer as a result of friction between the two main camps out there. I'm referring to the deep penetration people, which primarily consist of the IWBA and its supporters, and the..... normal penetration people which pretty much include the rest of the world. Comment deleted. Sure, I agree, normal is a subjective term, so is deep.....but some word has to be used to differentiate.....I thought I was being kind in refraining from the word, excessive. Comment deleted. Agreed.

I'm unsure of your feelings now regarding Mr. Fackler's inflexible philosophy of deep penetration, but both groups should be concerned over the confusion that's being created because the lives of peace officers are at stake here. As I see it, while Martin Fackler certainly possesses high credentials as a surgeon, he very much lacks credentials when it comes to determining which bullet types incapacitate quicker. Where are the results of his tests? Why hasn't he performed live animal tests? All anyone gets from Mr. Fackler is criticism. He turned his back on his own people, that's why he wasn't invited to participate in these tests. Comment deleted. Fair? Has he been fair? One of the things that few people are aware of.....including outside supporters and even members of the IWBA.....is that.....Mr. Fackler has repeatedly stepped on the toes of a lot of high-ranking army officials by acting as their self-appointed representative. The brass resents this and Martin Fackler has been disenfranchised by many of them because of his unsupported statements regarding stopping power. Since his retirement, Fackler has become more brazen and appears even more indifferent to their pleas that he disassociate his personal theories from army policy. One of the Strasbourg researchers personally knows Fackler and is extremely disappointed in him as a colleague.....that is, from an ethical standpoint. Basically, what has happened over the last six years or so is that Mr. Fackler has single-handedly created a schism within his own service branch.....and to be perfectly honest, I think all this boils down to a case of inflated self-esteem.....but, don't get me wrong, Mr. Fackler isn't the only one guilty of egocentricity. Because many of the writers and editors publicly committed themselves to one side or the other early on, they've made it tough on themselves to admit they were in error.....so the end result is.....pride forces them to remain entrenched. I think this is where character and responsible journalism should come into play. There collective motto should be.....if you're right, don't flaunt it, and if you're wrong, acknowledge it.....but by all means, work together. I think you'll concede that the law enforcement community would be much better served if editors and writers of trade journals or police-type magazines adopted a.....non-partisan position and simply weighed the facts logically, and reported them fairly. Comment deleted. Yes, I admit its idealistic, but only because ego prevents it from being a uniform reality. If honesty translates to idealism, we need more idealists. We have a problem.....the opinions expressed in these publications carry a lot of weight, sometimes more than they should.....and they're especially dangerous when they're subconsciously formed through affiliation or personal prejudice. Along this line, I'd be interested to hear your thoughts on how the rivalry among the various publications will affect.....prudent ammunition selection by law enforcement personnel. Comment deleted. That seems like an idealistic observation to me. I hope it proves to be accurate.
But getting back to the tests.....it was confirmed that incapacitation time was definitely linked to the degree of energy lost. The greater the energy loss, the higher the system pressure.....and if the system pressure is high enough, incapacitation occurs relatively quickly.....sometimes almost instantly. Comment deleted. No, I'm not disregarding the importance of penetration. I'm saying that the bullets that performed best, penetrated less than the equivalent of ten inches of bare gelatin. Bullets that penetrated very deeply, did very poorly. A bullet that over-penetrates is evidence of low energy loss.....and low system pressure. This is incredibly significant. Incredibly important. Incapacitation is brought about in only one of two ways.....high system pressure or high blood loss. A high energy bullet that expands very fast or a bullet that breaks up, creates both. A deep-penetrating bullet can't create high system pressure, and because of its low energy loss creates a minimal wound channel.....the thing directly responsible for blood loss. The slower the blood loss, the longer the incapacitation time. Except for the dimensions and consistency of the test medium, the SIFS study was right on the mark. Comment deleted. I don't believe it was discredited. Most of its detractors lacked credentials.....again, this is where professional envy and poetic license can destroy valid, but immature methodology. The Strasbourg results actually prove these people were on the right track in using energy loss as their prime equation.

I've probably used up enough of your time already, but one other important element of these tests was that the animals used harbored no.....psychological predisposition.....regarding the effect a weapon is supposed to have. This is extremely important.....it makes the study even more valuable. I hope I haven't offended you or bored you too badly. I'd better let you go. Comment deleted. The pleasure was mine.....thank you for letting me break into your schedule. Comment deleted. Really all we ask is that you reserve comment until all the evidence is weighed.....lives are at stake. Comment deleted. Yes sir, it'll be sent out this afternoon. Comment deleted. Thank you.....have a good day."

One shot stop?

Why do you need a one shot stop? I can't think of ANY gun someone would normally carry for self defense that doesn't hold at least 5 rounds. Even a derringer would hold 2.
 
You shootem until they stop movin! Seems to me the only attitude to take if you have to go to lethal force.

Stay Safe
 
Why do you need a one shot stop? I can't think of ANY gun someone would normally carry for self defense that doesn't hold at least 5 rounds. Even a derringer would hold 2.

Then don't tell my your .45 is better than my 9mm. That's where the whole of the arguments and disagreements come from.

Besides, I have a natural curiosity about how bullets work. Everyone seems to agree in interior ballistics and exterior ballistics, pretty straight forward how things work, no arguments, lots of knowns, fewer variables, good quantitative formulae to express the mechanics, the physics of it. Heck, even I have written programs to model what a bullet does in flight, exterior ballistics. The big question is terminal ballistics. I, for one, think it's interesting. I haven't changed my guns over any of it, but just as I use exterior ballistics to test loads in flight, it'd be fun to be able to do the same for terminal ballistics and it might just help bullet makers if they actually KNEW a way to model the workings of bullets in flesh.

I have the distinct feeling, though, that much as with Einstein's relativity, I might know the rough layman's causes and effects of some things, like the faster you go, the slower the clock relative to the rest of the universe, but I have no earthly comprehension of the math involved in proving it. :what: :D I reckon I could grasp how the bullet works, have a good idea now just listening to Dr. Courtney and have often though the process involved some such mechanism as the shock wave. It is, after all, all about energy transfer by SOME mechanism, but I couldn't even begin to do the math. :banghead:

But, so long as there are agendas, I fear the arguments will continue about terminal ballistics. :rolleyes: The facklerites and the Cooperites are firmly entrenched.
 
Because, Michael, in fifteen years, nobody has ever shown any evidence that Strausborg was anything but a complete lie. A fib. A fabrication. A trick to sell gun magazines.

How am I supposed to prove it didn't exist? You can't prove a negative. I also can't show you with 100% certainty that Santa Clause doesn't exist either. But as a reasonable man, I'm pretty sure he doesn't.

I could care less if future tests showed similar results. Doesn't change the fact that Strausborg is a complete pile of steaming crap that never really happened.

So your paper is going to show that M&S, although it is riddled with garbage, works hand in hand with goat tests that never actually happened. Good luck with that.

I was going to say something similar, but it looks like I got beaten to the punch. Michael, you do realize you're basically saying "well, this data that everyone thinks is fabricated correlates strongly with this other data that everyone thinks is fabricated, and also with our data which no one has seen, therefore none of them are fabricated"?

You're also ignoring the fact that MacPherson's tissue crushing equations have a very strong correlation with the Thompson/LaGarde cattle shooting tests, which, unlike the Strasbourg tests, are very thoroughly documented. The cattle consistently needed 0.22 grams of lung tissue crushed per pound of body mass to cause rapid incapacitation. By your standards (correlation with real shootings of animals), the Facklerite stance (crushing of tissue is the primary mechanism of handgun wounding) is 100% correct, and it's got more legitimate documentation.


But, so long as there are agendas, I fear the arguments will continue about terminal ballistics. The facklerites and the Cooperites are firmly entrenched.

So are the energy transfer junkies. You really need to go to your library and request an interlibrary loan for Bullet Penetration. It explains all of the physics behind bullet penetration.

Energy is involved in the stretching and compression of tissue, because elastic tissues act more or less like a spring, but it is primarily force and stress which make the hole.
 
You didn't answer my question. Why do you disagree with MacPherson's analysis?

My criteria for answering your question is that you summarize the analysis you have in mind in your own words. You posted references but have not summarized the points in your own words. I have several purposes is having this as a requirement for answering a question:
1. To keep the scope of the discussion limited to the points you find most compelling.
2. Not to waste my time by answering every objection to M&S that has been published simply because someone posts a reference. If you take the time to summarize the points in the reference, I will take the time to answer.
3. To ensure you understand what the reference is really saying. If you can't demonstrate an accurate understanding of the reference, you won't be able to understand a sound reply either.
4. If you summarize the important points, you cannot turn around and claim that I have committed the strawman fallacy by answering issues that the original author did not really raise or that are not the most important points.

There are disagreements as to what is a one-shot stop, and what isn't. For example, in the last M&S book, "Stopping Power," the .32 ACP "single mother" anecdote on pp. 242-243 does not appear to be a one-shot stop, as the bad guy was able to continue hostile activity after he was shot. Then there are anecdotes in which there are no witnesses to the bad guy's immediate reaction to being shot, for example: pp. 252-253 (Trooper/AR-15); p. 265 ("Federal .357 SIG 125-grain Failure").

Please show convincingly that the shooting events in these descriptions were included as data points in the OSS data set. M&S have clearly stated that not every event described in the short accounts in their books meets the selection criteria for inclusion in the data set from which their OSS statistics are derived. There are a number of multiple shot shootings in the brief shooting accounts as well, yet there is no reason to suspect that these were included in the OSS data. It is simply an unfounded presupposition on your part that all of the shooting event descriptions in the M&S books represent events that were included in the OSS data.

Your presuppositon is wrong. You are presupposing that the only way to "prove" that a scientific experiment occurred is with physical or documentary evidence of the actual experiments. This is simply wrong. Carefully controlled scientific experiments are best validated by repeatability. In other words, both the important findings and the experimental results are repeatable with experiments of similar design.

As long as the experimental procedure and data are reported, there is no need for documentary or physical evidence to have scientific certainty that a scientific result is valid. The findings and results merely need to be repeatable.

So we can ask with regard to the Strasbourg tests: "Has the principle finding that a pressure wave plays a role in incapacitation and injury been supported in later experiments?" The answer is a resounding "Yes!" Consider these references:

Knudsen SK, Oen EO: “Blast-induced neurotrauma in whales.” Neurosci Res. 46(3): 377-386 (2003).

In addition to these peer-reviewed papers supporting the pressure wave role in incapacitation and injury, our research group has conducted two separate live-animal research projects supporting the role of a ballistic pressure wave in incapacitation. In one project, we observe incapacitation of 10-20 lb mammals by a ballistic pressure wave without a wound channel even being present.

In addition your suggestion that an experiment is fraudulent simply because the researchers will not release video or strip chart data to the general public is absurd. Very, very few live animal research projects release video of their animals to the general public, and no one releases pictures or video in situations where the animal rights activists might interpret as animal suffering. Most live animal research is covered by non-disclosure agreements that limit what information can be released, and it is generally considered acceptable to release only sufficient information to allow the experiment to be verified by possible replication by independent research groups.

What I've seen just deer hunting over the years disagrees with your simplistic views on terminal ballistics. I've seen lung tissue turned to mush WAY away from the bullet's path. I've seen baseball size exit holes from a bullet that MAYBE expanded to 70 caliber, that's 0.70". I've been convinced since way before Fackler that there is more to it than lead meeting flesh. And, I fail to see how there's any sudden transition from bullet crushing flesh to massive energy transfer just from the added velocity of a rifle bullet. To me, seems logical that what works at 3000 fps, is still there in less amplitude at 1200 fps. I don' hunt with FMJ bullets and I don't rely on them for self defense, either.

Seems to me, if all that mattered was bullet crushing flesh and energy transfer was not what destroyed biomass, the shape and construction of the bullet would be moot. We could all rely on military ball for our deer hunting. And, the Chicxulub crater would be 6 miles across, not 150 miles.
 
Because, Michael, in fifteen years, nobody has ever shown any evidence that Strausborg was anything but a complete lie. A fib. A fabrication. A trick to sell gun magazines.

On the contrary, the Strasbourg finding that a pressure wave plays an important role in incapacitation and injury has considerable support both in work that was published before and in later experimental work.

How am I supposed to prove it didn't exist? You can't prove a negative. I also can't show you with 100% certainty that Santa Clause doesn't exist either. But as a reasonable man, I'm pretty sure he doesn't.

It is straightforward to prove fraud in the case of scientific experiments. If the original experiment is a fraud, attempts to replicate the experiment or reproduce the important findings with experiments with similar design will fail to do so. As I have already explained, Calling for documentation is a red herring.

If Strasbourg were a fraud, it would be easy to disprove: shooting a number of goats with the same loads under the same conditions would produces significantly different average incapacitation times. You wouldn't have to use all the different loads as the original tests: showing significantly different average incapacitation times for a small number of loads would be quite sufficient to prove Strasbourg a fraud.

So here we are, 15 years after the first suggestions that Strasbourg was a fraud, and no one has proven the accusation either with evidence (documentation) of fraud or by a failed attempt to reproduce the average incapacitation times. Yet over that same 15 year time period, the evidence supporting the Strasbourg finding that a pressure wave plays an important role in incapacitation and neural injury has been steadily increasing.

I could care less if future tests showed similar results. Doesn't change the fact that Strausborg is a complete pile of steaming crap that never really happened.

Repeatability is the very heart of scientific validity. Your suggestion that the Strasbourg tests are somehow repeatable even though they were fraudulent is a much more extraordinary claim than accepting them at face value.

So your paper is going to show that M&S, although it is riddled with garbage, works hand in hand with goat tests that never actually happened. Good luck with that.

The M&S OSS data set has some relatively minor weaknesses and errors, but interpreted correctly keeping in mind the accuracy-limiting factors, it does have value. The repeatability of the Strasbourg findings supports the validity of the M&S OSS data because they are well correlated. Your argument for "garbage" and "fraud" is even more strained because now your assertion requires believing that there are two "bad" experiments that somehow just got lucky in revealing an important pressure wave contribution to incapacitation that agrees pretty well with a growing and compelling body of later work.

Michael, you do realize you're basically saying "well, this data that everyone thinks is fabricated correlates strongly with this other data that everyone thinks is fabricated, and also with our data which no one has seen, therefore none of them are fabricated"?

This is the bandwagon fallacy.

First of all, not everyone thinks that Strasbourg and M&S are fabricated. There are a number of authors who have published works suggesting some degree of validity to M&S and Strasbourg, some are gun writers, others are engineers and scientists with significant technical training. In addition, I am working with a team of researchers with impressive credentials who has considered the issue carefully and concluded that neither work is fabricated. Finally, I have communicated privately with numerous doctors, scientists, and engineers who are convinced of the credibility of the M&S OSS data and the Strasbourg tests.

Regarding the research of our own group, our data is not yet published, but our results and data have been shared privately with a considerable number of medical professionals, scientists, and engineers as part of our review process prior to publication, so you are wrong to assert that "no one has seen" our data.

You're also ignoring the fact that MacPherson's tissue crushing equations have a very strong correlation with the Thompson/LaGarde cattle shooting tests, which, unlike the Strasbourg tests, are very thoroughly documented. The cattle consistently needed 0.22 grams of lung tissue crushed per pound of body mass to cause rapid incapacitation. By your standards (correlation with real shootings of animals), the Facklerite stance (crushing of tissue is the primary mechanism of handgun wounding) is 100% correct, and it's got more legitimate documentation.

MacPherson's work on bullet penetration is sound. The only weakness is the unverified presupposition that easily detectable wounding is the only contributor to incapacitation. Incapacitation rather than easily detectable wounding defines handgun bullet effectiveness, and there is ample evidence in the peer-reviewed literature that a pressure wave can cause obvious incapacitation via neurological injury mechanisms that require advanced techniques to detect.

The Thompson/Lagarde tests occured in cattle, a species where a much higher pressure wave threshold is likely to be needed to produce incapacitating effects, and with bullets producing much lower pressure waves than some handgun bullets produce today. In other words, even though both pressure wave and tissue crushing effect produce incapacitation effects in human-sized animals, increasing the size of the animal by a factor of 5 and reducing the pressure wave magnitude by a factor of 3 will result in only seeing the effects of crushed tissue.

So are the energy transfer junkies. You really need to go to your library and request an interlibrary loan for Bullet Penetration. It explains all of the physics behind bullet penetration.

I own the book and have a PhD in Physics from MIT. The Physics presented behind bullet penetration is sound. However, there is nothing in the book which is scientifically conclusive about a pressure wave mechanism in incapacitation.

Energy is involved in the stretching and compression of tissue, because elastic tissues act more or less like a spring, but it is primarily force and stress which make the hole.

Sure, but this does not address the possibility that something beyond the hole might be contributing to rapid incapacitation.

The Fackler camp is over committed to the unproven presupposition that only the hole can contribute to rapid incapacitation. In light of the advances in neurology in the last 15 years, we now know that a pressure wave can create incapacitation and neural injury. If the M&S work is so bad, then why is it that it correlates well with models that include both the pressure wave and size of the hole as possible mechanisms, but poorly with models that include only the size of the hole?

What I've seen just deer hunting over the years disagrees with your simplistic views on terminal ballistics. I've seen lung tissue turned to mush WAY away from the bullet's path. I've seen baseball size exit holes from a bullet that MAYBE expanded to 70 caliber, that's 0.70". I've been convinced since way before Fackler that there is more to it than lead meeting flesh. And, I fail to see how there's any sudden transition from bullet crushing flesh to massive energy transfer just from the added velocity of a rifle bullet. To me, seems logical that what works at 3000 fps, is still there in less amplitude at 1200 fps. I don' hunt with FMJ bullets and I don't rely on them for self defense, either.

Apparently you aren't too familiar with Fackler's work, and are trying to simplfy things into a single issue. Fragmentation and temporary cavity size are significant factors in tearing of tissue, at rifle velocities.

At handgun velocities, the permanent crush cavity is the primary detectable mechanism of wounding. At handgun velocities, there just isn't enough of a temporary cavity to cause a large amount of tearing, even with substantial fragmentation.

What Michael Courtney is talking about is damage to the nervous system which is undetectable without microscopes, not the shredding and tearing of tissue due to temporary cavitation. Pressure waves have nothing to do with that; the temporary cavity causes both tearing and pressure waves, not vice-versa in any direction.

Crush Cavities

Just one reason why LSWC in .45acp in my view is a much better bullet than a 230 gr RN FMJ! another reason why we carry them cast hard for bears in our .45acp's.

As for energy transfer at handgun velocities. The effect of being shot with a handgun has been described by one receipient as "like being hit by a baseball" others were not even aware they were shot. Not much energy transfer me thinks.

Take Care
 
Its been years since I studied statistics but I still have my copy of

"How to Lie With Statistics" by Darrell Huff. Well worth reading.

Anyway, M&S were very selective in chosing which cases to include in their study. Being very selective gave them the opportunity to 'prove' any point they desired. For that reason alone, I think the M&S study should be trashed.
