As mentioned above, the temporary stretch cavity for handgun calibers is moot. The TSC has to get beyond a certain size for it to result in stretching actual tissue in human beings (and animals) to the point where it causes damage. That's why rifles are rifles, and pistols are pistols...because a rifle projectile moving much faster does stretch tissue past the point of its elasticity and tears it. Thus with a rifle the bigger the TSC the more tearing of tissue you get, which is a significant contributor to the wounding potential of that round.

No such luck with handguns, as none of them create a large enough TSC for the stretch to contribute to the wounding potential of the round.


And honestly, if Fail-Safe does know where reputable online database


There's no such database available to the general public in terms of aggregating wound ballistics information. Sections of the FBI and the DOD have collected quite a bit of information...but they tend to be limited on who they give the data to. Individual departments also collect data on the shootings their personnel have been involved in, but sharing of that data is also limited. If you have LE credentials and the right contacts, though, you can get access to it.

Something you previously mentioned stuck out to me:


Fackler pushes penetration and ballistics gelatin. Ballistic Gel is a good indicator of how a round/caliber/weapon will act in human flesh, but it is not iron clad. The human body does strange things and I’ve personally witnessed a human male shot at close range with a 165 Gr 40 Cal Hydroshock in the skull, with penetration into the skull, get up off the floor and fight me for 2 minutes until back up arrived to help me take him into custody.


There's actually nothing at all unusual about that incident. There have been many like it in the past...something that those folks who aggregate shooting data have noted. A non-penetrating hit to the hard curved surfaces of the skull can cause the bullet to ride along the curvature of the skull and do no significant damage. Handgun rounds have a tendency to produce this effect moreso than rifle rounds. This is why the advice from IWBA experts has been to aim for the ocular window, as rounds placed there penetrate and hit the important stuff.



Thanks for the info JW777.
BTW, the bullet penetrated the skull. I saw the hole and it was confirmed by the ER surgeon who worked on him afterwards. The 'Do Rag" the guy was wearing actually saved his life according the doc...somehow it clotted the wound and prevented him from bleeding out. He still fought like a sonofabitch...I'll give him that much.

Kudos to you for trying at least. Most wouldnt. They'd stop with just bad mouthing others on the internet.

I dont carry a recorder when I speak with TX DPS Troopers and Rangers. How many have you spoken with? The video I mentioned is no longer on Youtube, that or my Youtube search skills suck. The poster of that video was "Toyota4x4" or something like that. That said, the bullet TX DPS was using was a 230gr JHP. I have been told it was Federal Hi-Shok, but have no absolute source on that. They now use 230gr Speer GDHP in those pistols that are chambered in .45acp.
Last Texas PDS officer I spoke with was in 1996. I had just gotten out of the Corps and was driving back home to St Louis. He felt I was driving a bit fast, and that's how we met. At the time, trying to talk my way out of a ticket was more important that discussing what weapon and round he was carrying. Seeing as how I'm a cop here in StL, I probably wont get a chance to speak with one in person for quite awhile.

Its my pleasure. Thats what I hope to do here, inform. There are maybe another 5-8 links to papers destroying Marshall & Sanow credibility. Note, that while I do not accept what was put out, I still find Evan Marshall to be a nice, pleasant man.
I've never met Marshall, Sanow, or Mas Ayoob. I have however spoken with him online. He seems nice enough.
I do thank you for the links and I will continue to research more.

Not really. The IWBA had a passion for wounds ballistics. The IWBA was composed of trauma surgeons, medical examiners, police officers, and military officials from all over the world. All sharing what they had seen in hospitals, mourges, on the streets, on the battlefields, and in simulated testing. Some of the people you mention as associates were not with IWBA at the time of their papers. Also, the mathematical dept at the University of Tennessee had no connection to Marshall & Sanow or the IWBA. However when all the Marshall & Sanow books were brought to their dept for review, they found it impossible to draw the conclusions that M&S where drawing.

I did a search on Duncan McPherson after your forst post, (author of 2nd link you posted against M&S). One of the links pulled up a review filled an amazing amount of praise for him by none other than Dr Fackler...made me more than suspicious about McPherson's objectivity. Univ of Tenn is obviously a different critter all together.

I dont know where you are getting the "axe to grind" issue. All the IWBA cared about was truth in wounds ballistics. At the time of those publication, Dr Fackler (at the time Lt Col USA) was being labeled as a"jello junkie" by M&S and Ayoob (who is responsible for getting Evan Marshall and Ed Sanow together and telling them what he wanted), while not mentioning his work in Vietnam as a surgeon.

The axe to grind issue comes from the venom he showed in attacking their findings. I'm not saying it wasnt deserved, but you have to understand that he begins to distort his appearance of objectivity by making personal attacks in his findings. I dont know if you are or were LE, but when I get two people telling me the other did something, generally the one who appears to be the most calm and least hysterical gets listened to first. Not saying Fackler was hysterical, but you get the point. Until I can wade through the statements made by both, the one who appears to be the most calm and collected and states the facts gets listened to first...I've been wrong before, and it appears that this is one those times as well. Hope that makes sense....might not come off over the computer screen as well its meant.

They are just stating what they have found.


The problem is they dont. They have published misleading, and down right false anecdotes in their books (I mentioned earlier the Amarillo, TX PD and Toledo, OH PD being the most disgusting of the claims). When members of each of those depts wrote to the editors, they were brushed aside.
Then that's just wrong, no two ways about it.

Kenneth Baumruk was shot in the head twice with 45 ACP rounds, ( I don’t know what weight or make of bullet) and survived just fine. One of my instructors in the Police Academy was the officer that shot him with a S&W 4506.


Penetration is pushed as most critical because without it you have nothing. Which has a better chance of incapacitating a bad guy, a shot that stops 2 inches from the heart, or one that severs it? Obviously the latter. The only guarantees in stopping a bad guy are a CNS hit or exsanguination. the former does it quickly. "Lack of penetration gets good guys killed".

Keep in mind some things about the structure of the cranial vault. Its made of very strong bone that is angular. Pistol rounds, no matter the caliber, have been known to be deflected off the the skull. An Arlington, TX PD officer was shot in the head a couple of weeks ago, by a badguy. The bullet hit above his right eye, deflected, and exited near his right ear. He's fine.

Penetration is critical, but too much penetration can cause problems too. Otherwise we'd just shoot FMJ.
I'm familiar with human anatomy & physiology. I stumbled in LE work all sorts of bass ackwards...Long story short is that I was intending to be a fire fighter here in StL and was within a few weeks of obtaining my paramedic license when I was contacted by the police department and offered a job. I took it with the intention of doing a year, and then transferring over to the FD, (StL FD gives preferential hiring treatment to city employees...so it made sense to put in an application with them at the time while I was waiting on the FD Hiring Process), two weeks in the academy I was hooked. So I do have a familiarity with human A&P, but I was no doctor nor do I pretend to be.

In this particular case, the shot struck above the left eye at the hairline. It penetrated the skull and caused the suspect to lose conciousness and fall down a flight of stairs. Since the court case is still pending, I will not post anything that might wind up in court somehow. Suffice it to say, I got a very, very good look at the wound and it absolutely penetrated the skull and did not exit nor did it hit anything that shut him down for more than a few seconds. After the trial next month, (assuming it doesnt get pushed back yet again), I will post up an AAR here on ARFcom detailing the shooting and the several mistakes that were made by me and others on the scene in the hopes that they can be avoided by others. If you like, I will IM you when this happens and send a link to the thread.

The first is actually a gelatin shoot of the round.

http://www.youtube.com/watch?v=W9iiaXoRaRY


Here's the problem with that tester, and the tester himself. He doesnt know the difference between a Permanent Crush Cavity(PCC) and the Temporary Stretch Cavity(TSC). The is obvious when he says "Permanent Stretch Cavity". That big area you see is actually the TSC. It is called that for a reason. The reason is that the elasticity of human flesh is enough to overcome pistol TSC. It is not considered a wounding factor at all.

As for the gelatin used, it is not calibrated 10% ordnance gelatin. The particular gelatin he used, is used to test the affects of bullets and body armor.

Thank you. I had not known that.

That is a link to an article that includes paragraphs from an article written over ten years ago. It was full of incorrect comments then as it is now. Criticizing "sterile lab tests" which is a criticism of Fackler, without knowing who else or what else has been done is silly and childish.

There's nothing there with any technical data. Just some folks saying what they like and why

Agreed. Hence me asking you for a database where such information is available.Very, very, very few people post with all the information necessary. Here on the board, Molon is the only one I've seen post with what could honestly be called data. Everyone else, (myself included) seems to be posting anecdotes.

Same as before. They talk about why they like it, but cant say why. You have that guy named CTG Collector who will always tell you its a great round, but like many others, cant say why. Oh! It goes fast, forgot about that! ;D

There are documented one shot stops by LE agencies on both people and dogs, using the 357 Sig. I've never shot one, but from what I've read, that thing hits like a ton of bricks.


Can you link us to the documented accounts?



Keep in mind some things about the Glocks chambered in .357sig (.357auto to Gaston). They are generally not the most durable of firearm. In fact New Mexico State Police has had their fair share of problems with them. They switched to the M&P. JW_777 has a information regarding their armory being full of G31s with cracked frames that Glock refuses to warranty. Glock also puts the lifespan of these pistols at well under 20,000. Paul Howe also noted in his briefings that his G31 wasnt very reliable in the small amount of sand his pistol would get into at his range.



No, I cannot. I was using the information from Sanow and Marshall, and reports from Mas Ayoob.
Again, I’m unable to locate any place that has compilations of shootings that documents what round, caliber, and weapon they used to do so. If you have access to one I’d love to see it.

I have heard similar things regarding the Glock 357 Sig models. So at least we’ve got that in common….


Yeah, I dont think you're going to find anything like that unless you use your LE creds to call around to depts and ask. The problem with M&S and Ayoob is they accept second, third, fourth, etc hand information as fact. Or they make up their own facts.[/quote]

I dont think there is anyone out here collecting such information. Asking around out here wouldnt get me much.

I speak with them frequently. I have family at a large county jail in North Texas, and the bring their prisoners to them and speak with them. As I usually bring said family members lunch, I in turn speak with the Troopers and Rangers on occasion. Its fun to give the Troopers crap about writing their own mothers speeding tickets.

And? Duncan MacPherson knows what he is talking about. He has written a peer reviewed and internationally accepted book on wounds ballistics. Just because Fackler agrees with him doesnt mean there is some shadiness or underhandedness to him or his work.

Quite frankly I dont understand your disdain of Fackler. He is the father of modern terminal ballistics. Instead he has been vilified in popular gun press as a "Jello Junkie", discounting the fact that he actually served his country, repairing what war does to human bodies. Its that kind of experience that makes his research so valuable.

I think you are reading too much into his words. When you debunk someone's papers, quotes, articles, and books you do it with fact. He did that. Attacking someone's papers, quotes, articles, and books is nothing new. Its gone on for years, it goes on now. However you must keep in mind that ammo selection is critical. Poorly performing ammo, even with good accuracy, cant still get good guys killed. Therefore there's a lot more at stake than just who is right and who is wrong on the subject. That said, having read the papers, over and over, I dont see the "venom" you do. I see it as calling a spade a spade.

Sure, too much penetration is bad. However keep in mind the reason the penetration standards are what they are, are not just from head on torso with no obstructions. They are there for oblique angle shots, as well as shots that must defeat a limb before reaching the torso, and furthermore, they are set to reach the Central Nervous System, not just the vital organs.

OK, so the bullet entered the skull. I never doubted your comments. It just goes to show the human being can soak up an enormous amount of damage and continue to function at a high level. One must note that that portion of the brain can sustain massive damage and the keep "ticking". There is a little girl who is going on 10 years of age that had half of her brain removed 5 years ago.

I get that, but that info came from your link. Page 2, no less.

Also, keep in mind, bumping up the velocity of a bullet does not make a bullet better. In fact it can make it worse. Afterall, the difference between 9BP and 9BPLE is not bullet shape or design, its roughly 100fps. What 9BP does, its a safe assumption 9BPLE will do. Keep in mind, 9BP and 9BPLE were designed when things like wax, mud, and duxseal were used as tissue simulants, and clothing was not a factor. Note Dr Roberts's own words on the findings, the results do not include those bullets which failed to expand and zipped the entire block. That would be the too much penetration you were worried about above.
Because bite me, this is the internet. I will shit myself the length and breadth of its bandwidth willy-nilly, leaving little nuggets of my wisdom wherever the fuck I wish.

I was a devotee of Marshall/Sanow. I was deeply disappointed when I read of the discrepancies, and threw away my books when I saw how convincingly their findings were refuted. Last nail in the coffin was a statistical analysis of their percentages, which showed the findings to be impossibly orderly.

Nice guys, but it just didn't wash for me.

sad.
