Conspicuously absent from the website you linked to is the fact that Courtney never contracted with a military branch/LEA to perform terminal ballistic research.Duncan MacPherson is an MIT educated engineer as well as a disciple of Martin Fackler who's emphasis is little more than penetration being the answer to the question of handgun stopping power with nothing really new or persuasive on the issue.
Better to look at the research conducted by an MIT educated PHd in physics who can describe exactly what the effects of energy are and not just theorize with nothing more conclusive than gelatin testing. There have been 33 autopsies conducted that conclude that Dr. Courtney is on to something very important to those who will listen. I encourage anyone who can drop their bias for a second and consider the information presented to look at: http://www.btgresearch.org/wb.htm
And as to regards concerning the .357 SIG, it is the caliber used by the Texas DPS and the US Secret Sevice. No other agency has more actual gunfighting experience than the Texas DPS/Rangers. That's a historical fact rather than a biased opinion. Take a look at the results at www.m4carbine.net, it's pretty clear what loads perform and what doesn't and this from a listing advocated by another Fackler disciple, Dentist "Doc" Roberts.
I also enjoy bullet testing through a multitude of different intermediate barriers, including bone. While it would be better to use fresh cow or pig bones from a slaughter house, dried out range cow bones are more economical and abundant for me to test; plus these bones are very demanding on bullet design/construction.Alright, not sure if I'll be tarred and feathered for this or not, but I'm not a big fan of the "FBI standard testing". Sure the calibrated gelatin probably gives a decent enough representation of soft tissue penetration. For me personally that doesn't mean much. I would like to see more data with rib/bone penetration. Lets face it, if you hit where you are taught (COM) then the bullet will most likely have to penetrate sternum and/or ribs plus far enough to severly damage the heart or lungs. From the small testing that I have done personally has lead me to the conclusion that while the ideal is to have both good expansion and penetration, I lean more towards the penetration factor. I have learned through my own testing through my main carry gun that Hornady XTP for instance is not a good choice for me, great expansion but to little penetration for my likings.
The data we get from the FBI and similar tests are good for what they are worth. The best advise I can say is to do your own tests and see what works best for what you want it to accomplish with the gun you will be using it in.
You guys don't seem to be applying simple medical knowledge to your assertions.
...yet some animals (humans are animals too after all) are imediatly incapcitated from a chest shot even though there is no direct CNS damage.
BPW and the temporary wound channel are both very much capable of being signifigant means of incapcitation.
Fackler was a fool to claim 2000fps was a magic # for TWC to be meaningful, when he should have known dang good and well that 1500 is more than enough for TWC to be meaningful and yet 3000 doesn't guarentee that TWC will be meaningful.
For the record I'm definately not advocating using energy as an important determining factor. Placement, penatration and expansion all take precident but to ignore it or say it's not a factor is IMHO foolish.

FWIW, I personally asked Courtney this question before he began using the pseudonym of Pasteur.

I agree. The first meaningful (to me) information that I've seen is the work done by BTG Research that explains what the effect of kinetic energy actually means in wound ballistics. http://www.btgresearch.org/wb.htm
"DocGKR and I--as well as many other learned persons with experience in scientific research--have independently spent hours and hours looking up Courtney's citations to be sure we're not missing something important, and we have independently come to the conclusion that his work is junk science at best. Feel free to keep researching and arguing with Courtney, if you like, but in the end you may feel you've wasted a lot of time and energy that could have been used more productively in other pursuits. Arguing with Courtney is like trying to teach a pig to sing..."
When I first ventured into the study of terminal ballistics over a decade ago I had already been practicing as a trauma physician for quite some time... but that didn't make me a ballistician. I realized very quickly that I had a LOT of reading to do before I would be in any kind of position to offer opinions on wound ballistics in any forum: in court, at trauma grand rounds, or on internet bulletin boards. I would like to encourage you to try to get grounded in the necessary disciplines before you go chasing after someone like Dr. Courtney, who by all appearances is a brilliant--if eccentric and often misguided--man. You won't be able to find the errors in his papers/writings unless you've got enough pertinent background knowledge, so I'd suggest you dust off your library card and get to work.
Take the time to read the referenced articles--they do not support the claims of this paper. For that matter, the clinical evidence and outcomes of thousands of patients treated for GSW's and hits to body armor in recent combat clearly highlight the irrelevance of this paper, as do the numerous patients treated for domestic GSW's in this Nation.
And as to regards concerning the .357 SIG, it is the caliber used by the Texas DPS and the US Secret Sevice. No other agency has more actual gunfighting experience than the Texas DPS/Rangers.

Also of interest is that both Dr Fackler and Dr Roberts have been employed in that capacity by several different organizations under that category both having worked at Letterman Army Institue of Research, Division of Military Trauma Research and a few others.
"bpw" ?Borland Pascal for Windows?
Board of Public Works?
Basal Pulse Width?
Sorry, couldn't resist.
This is a great discussion, learning a lot. Thanks.
There are other factors involved in producing reliable rapid incapacitation. Your prejudice blinds you to other equally important factors that have been well articulated by Fackler:
1) Adequate penetration.
2) To reach and damage vitals that are critical to immediate survival.
3) Amount of damage produced in critical tissues (wound severity).
Reliable rapid incapacitation is caused only by what vital structure(s) a JHP handgun bullet comes into direct contact with and how much damage it produces to that structure (wound severity). TYPE of tissue and AMOUNT of damage are what's important.
Show me one single case where I have disagreed with 1, 2 or 3.
And as for other opinions, there was research conducted by others like Sorensen et al that preceded Martin Fackler yet he chose to ignore it.
It’s titled “Relative Incapacitation BULListics”. It was reprinted in IWBA Wound Ballistics Review, Volume 1, Number 2. PM me if you’d like a copy.
You consistently omit 2 & 3 in your rants.
English. Fackler hasn't provided anything of importance to the issue. Instead, he led the FBI down the rosy path of ammunition failures with the subsonic over-penetrating poor expanding 147 gr. JHP in 9mm of the late 80s. The over-penetrating poor expanding 10mm "Lite" that followed and for an encore, it was the "medium velocity 165 gr. JHP in .40 S&W.
I addressed, last month, the exact same misinformation you're posting in this thread. See - http://www.thehighroad.org/showpost....2&postcount=94
Again, you fail to show where I disagree with points 1, 2 or 3.
