Generally I lurk more than I post, but something has motivated me to post some comments that I think are of an important nature. They have to do with the results of penetration tests for various loads and firearms and how those who run them interpret their results.

What has me hacked right at the moment is the conflict between results presented from the Box of Truth website versus the results on a DVD that comes from the Valhalla Training Center sent both by the NRA and I believe the SAC regarding personal firearms training and how to deal with self-defense issues. The segment I am talking about is a bonus feature on one of DVDs that has one of the expert instructors talking about what will penetrate through so many walls and open spaces and then recommends you select this or that for a home defense round and gun.

Box of truth, for example, states that birdshot is a poor penetrator and also a poor defense load. the VTC expert stated that because of the minimal wall penetration it would make an excellent self-defense load out of a 12 gauge, but recommended that a 20 gauge or .410 shotgun would be even better.

The VTC also recommended using Glazer safety slugs as your self-defense loads as they were also less likely to penetrate as far as a JHP or a solid lead projectile. Perhaps I am mistaken, but aren't those rounds a little expensive to purchase and practice with so that you know how they perform in your firearm and can be certain they are will work reliably?

I understand being concerned about liability issues and what bullet might do if it misses the attacker or if it exits out the far side, but some of the recommendations for loads by VTC seemed to be a bit on the crazy side.

I also thought it was interesting that the same instructor, in another bonus feature, explained what made the best gun for self-defense, not the one you have in your possession at the time, not the one that you are experienced in shooting and already have, but you have to buy a Glock or Glock-like design that has no hammer, no safety that requires external deactivation and no decocker or such to have it be made ready to fire or to make it safe to reholster.

That same person did not recommend revolvers, anything smaller than 9mm, anything larger than .40 caliber, anything that looked or acted like a 1911 or anything that had a barrel longer than about 3.5 inches or might even be a target configuration and it also shouldn't be mostly steel or alloy, rather it should be lightweight polymer. It was not stated directly, but that is what is indicated by how he talked about the selection of a firearm. I understand the concept of an ideal type of firearm, but individuals, situations and finances are far from ideal.

What this makes me wonder is, how are you supposed to know what is truth and what is opinion or fiction unless you have the time and resources to do your own independent tests? Is Box of Truth wrong or is the VTC instructor wrong or are both right or both wrong? Or is it really just a matter of opinion that can really never have any real answer?
 
Did the credits at the end of the video look something like this?

Blastin' that same wascaly wabbit, over and over again, since 1932.

Valhalla Training Center? Is that a mall ninja school, perhaps?
 
The Valhalla Training Center is a state-of-the art shooting school in Colorado run by Rob Pincus, who is also on staff with SWAT Magazine.

Having been there, I can tell you that it is one of the most phenomenal facilities for learning combat shooting, and run by a guy who knows what he's doing.

I can't speak to the video in question as I haven't seen it. However, while Box of Truth is a good website with some useful information, some of their methods tend to be a bit shade tree.
 
I'm not familiar with Valhalla but the bit about penetration is going to one of those things that you're going to have to make a decision for on your own. The stuff the box of truth guys write about penetration is the same thing you'll hear from the people that are considered to be the current experts in ballistics like fackler and roberts and also the principles that most LE groups like the FBI operate on. Personally I'm going with the opinion of doctors who have expertise in this area when they say that glaser rounds and birdshot suck. Ymmv.

I'm sure its possible for someone to be able to teach good shooting techniques without being up to speed on the last 20 years of ballistics research. I wouldn't take a class from someone that fell that far behind in their field, but again, ymmv. There are also schools that are big on the "that gun is all wrong for you....you need a glock." I don't want a class from someone that thinks the specific brand of handgun is that high up on the list of important things in training. I want the instructor that is going to teach good techniques and mindset that is applicable to any reliable handgun that I can shoot well.
 
FWIW, I've done some penetration stuff myself - I'm VERY happy with a light load of #8 birdshot (actually AA "featherweight" light skeet loads) in a 12 gauge... At 7 yards from a short barrel I get about 6" of "hamburger" pattern, and it only makes it through one side of a sheetrock wall. But that side is nothing but a big hole. Pellets are all trapped (with a few under the paper) on the other side.

I would NOT want to be standing in front of it at 7 yards or closer.

And, more importantly, I wouldn't hesitate to unload it in a house with friendlies present, but a clear target.

As for handguns - buy one that "fits" you ergonomically, and which points naturally for you.
 
UnintendedConsequences What this makes me wonder is, how are you supposed to know what is truth and what is opinion or fiction unless you have the time and resources to do your own independent tests? Is Box of Truth wrong or is the VTC instructor wrong or are both right or both wrong? Or is it really just a matter of opinion that can really never have any real answer?
The answer to your question is found within the question; they are both right, they are both wrong.
From a testing standpoint, test conclusions are only pertinent to the conditions under which the test was conducted. Coming from an automotive engineering background, I confine my examples to my realm of expertise. If I test an engine for peak power and torque in Thompson, Manitoba at -40 F, the results indicate little about the exact same engine tested in Mesa, Arizona at 115 F. Both tests are valid, both tests provide repeatable data, but the tests on the same engine will lead one to vastly different answers.

Testing done by the professionals at Valhala, and tests conducted by the old, retired guys at Box O' Truth both result in valid conclusions, but those conclusions are only valid for the conditions under which the tests were conducted.

Ballistics testing results in a lot of opinions being passed off as fact, the short answer is that there are no absolutes. Look at the tests as conducted, try to evaluate how those results pertain to your situation, read the conclusions (and remember, the conclusions are really only the opinions and facts as interpreted of the one writing the report) and try to make a decision that will be relevant to your conditions of operation.

In redneck terms (my prefered method of communication!) just because Bobby likes Kentucky Fried Chicken and thinks it's the finest chicken in the world, doesn't mean that I'm going to enjoy chokin' it down; I think KFC is low-grade hog slop. Popeye's Chicken is popular in the inner-sphinctum of Detroit, but in the outlying cities is a rare sight.

So, take two of these :banghead: :banghead: and try not to take the test results too seriously. :)
 
Cheney's hunting partner took a load to the face from 30 yards and is still alive. That was all the testing I needed to conlude birdshot is for birds.

Think he'd still be around is he used buckshot?

I don't know bout that! How many rounds of 7.92x57 did Bob Dole take and survive?
 
VTC expert stated that because of the minimal wall penetration it would make an excellent self-defense load out of a 12 gauge, but recommended that a 20 gauge or .410 shotgun would be even better.
Maybe if you found yourself in a real-life situation of alfred hitchcock's "The Birds" or a really uncomitted, clean, and sober intruder. Not long ago there was a news story of an older guy holed up in his room with his grandson who shot a home invader a couple times with a .410 and was forced to switch to his 30-06 hunting rifle to stop the guy from advancing.
 
For that reason you just mentioned, about the .410, is why I was simply take aback by the recommendation. I am not as much an expert as the VTC person, but I do know that birdshot does not penetrate as much as buckshot or a solid slug. I also know, from first hand experience that a 20 gauge and .410 might take game within appropriate limits, but they don't produce the same results downrange that a 12 gauge does due to a lighter or slower load.
 
I don't know much about VTC, but I like the "shade tree" methods of box-o-truth.

I suspect that both are right, from their own perspectives.

Just like ballistic gelatin testing both tells you a lot, and not much at all from the same test.
 
I'm in no way shape or form an expert anything, but if an instructor is telling me that the "best" self defense gun is a striker fired, polymer frame, semi-automatic in either 9mm or .40 S&W, I gotta say he's full of himself, and maybe wonder if he's getting paid by people that make those pistols.
Now that doesn't mean it's not the best gun for HIM. It means the best gun for him may not be the best one for me.
The best gun for YOU is the gun that YOU shoot well, and that YOU are the most comfortable using.
Just my opinion, and worth exactly what you paid for it:)

I would not be impugning their character. people can believe things that other people do not without the presence of an ulterior motive.

I think for most people a Glock type firearm in 9mm or 40sw is a pretty good choice. simple to use, reliable, and relatively inexpensive, and very capable of protecting your life if needed. I am not sure it is the best choice for everyone.

a lot goes into the choice of a defensive handgun. someone with little in the way of funds but who already owns a 4" 38 special revolver, and is reasonably proficient with it, may find that is his best choice.
 
Is VTC running students through their courses with glaser safety rounds and birdshot? There is minimal penetration, and minimal useful penetration. If there are extensive, credible studies done by the FBI or similar on the suitability of the glaser and birdshot rounds, it would lend that opinion more credence. It would give the VTC more credibility if they're running their students through courses with aforementioned ammo suggested by the DVD. However on what I would believe to be a common sense level, birdshot and glaser don't appear to pack much of a wallop. That glaser stuff also looks like it might not feed reliably in a semi-auto due to the cylindrical plastic casing shape; correct me if I'm wrong.

People say "if you do it right, you only need one shot", but arguably in a self-defense situation, most of the time you aren't shooting at a static target, and you aren't going to get a chance to do a perfect weaver or isosceles stance, gain a perfect sight picture under the situation. You're going to be fighting, stressing about the situation, and worried about your environment and where you are with respect to the threat.

As far as firearms selection goes...you've got the polymer pistol guys, the 1911 guys, and the revolver guys. They all make good arguments. They all have good track records. It comes down to personal preference.
 
Birdshot in a 12ga?

Seriously? Are we hoping that the intruder isn't wearing a leather coat? #4 Buck as a minimum if you want to do anything other than seriously piss off your attacker.
 
What this makes me wonder is, how are you supposed to know what is truth and what is opinion or fiction unless you have the time and resources to do your own independent tests?
It is all opinion until you have used the ammunition and firearm to successfully defend yourself. Only then is it truth, because then it is history. Whether the same equipment will save your life again in the future is still opinion. That is the truth. Software trumps hardware...........And that's opinion too. ;)

Me, I load my defensive shotguns with low recoil buckshot. I'm of the opinion low recoil buckshot would display superior performance over birdshot in stopping a crackhead intent on killing me.
 
The problem with any instruction is you need to know the underlying assumptions being made in the course of instruction. Many instructors seem to feel that their students will be unduly confused by a discussion of why something is taught a certain way and so they leave that portion out or greatly oversimplify it.

I know Rob Pincus has a lot of training under his belt and that Valhalla has great facilities. I don't know why they reached those conclusions on the video.

Personally I have reached the opposite conclusion on Glasers. Not only do they underpenetrate on ballistics gel; but when our own JE223 (Brassfetcher) tested them, they were actually MORE dangerous after passing through sheetrock because they stopped breaking up and got better penetration in gel.

I don't care for birdshot for the same reason. 4-5" of penetration sounds like more than enough to get the job done if you imagine you are shooting at the FBI silhouette target. After all, your target is unlikely to be much farther than 7yds indoors and the heart is less than 4-5" deep. Except that unlike ballistics gel, the heart has the sternum and ribs protecting it. And unlike the range, you may not get an unobstructed frontal shot. A side profile or an intervening arm can easily eat up that 5" of ballistics gel penetration.

In one case we discussed here, two men had a shotgun fight inside using household appliances as cover. One man survived because the refrigerator he was using as cover stopped the birdshot nicely. His buckshot penetrated the other man's concealment with no problem.

I personally would not make those same recommendations; but perhaps with a certain training regimen those choices may make sense if you understand and can execute the underlying doctrine behind them.

Self absorbed instructors, in any field, are a pet peeve of mine.
Based on what the OP said, that's what this guys sounds like to me.
I don't think it's wrong for him to say what works for him, (in fact he should).
I DO think it's wrong when when it's presented as gospel, equally applicable to everyone.

I agree 100%

Think he'd still be around is he used buckshot?

and how many self defense shots do you expect to take at 30 yards?
 
Aren't they both saying birdshot is a poor penetrator?

It seems to me Valhalla is saying that poor penetration is a good thing in some contexts, and Box is saying it's a bad thing in some other contexts. Can't they both be right?

What's the contradiction?
 
If we don't know things for ourselves then we depend on the words of "experts" to make decissions. Like finding a good mechanic or a good doctor all you can go on is previouse service to other customers. Or become the expert and solve the problem.
