I've been told that the 5.7 round will not penetrate a skull. that all though one blaze of a headache no penetration will accrue? I'd like to carry my 5.7 W/195 AMMO for a carry weapon but now hesitate. Does anyone have good info on this?

The reason for my concern is that a friend of a friend (not that I agree with what he did but he did it so) said that he tried to put down his dying dog by shooting it in the head with his 5-7 and it bounced off/ did not penetrate. Yah it was a dumb thing to do I didn’t do but it raised questions.

Sounds like a gunshop story. If it bounced, he probably had a glancing shot. Skulls are tough, and some dogs can be tougher than people.

yah I am calling BS on this the 5.7x28 in no way would have bounced off..

The 'friend of a friend' deal doesn't sound very credible.

I've read a number of police reports over the years where handgun rds have failed to penetrate the human skull at close range. The two that come to mind are a .25ACP FMJ that just imbedded slightly in the front of the skull and a .45ACP FMJ that hit the front of the skull but then followed the curve of the skull under the skin, exiting at the rear. Left a helluva nasty looking surface wound a the front, the EMT's on the scene thought the guy was dead for sure until he started moaning.
Handgun bullet not penetrating a dog's skull? I believe it's plausible depending upon the dog (ie: size/thickness of skull), the handgun rd used and the angle of the bullet.

I also have heard those storys also 25acp /45acp both are very slow rounds by nature.... in fact there was a dog intown that charged an officer it was shot with a faster 9mm right in the head turned around and ran half a block before it died.... so ok its is maybe a fluke but i would bet if he put it to his own head it would pop like a mellon :lol:

I've worked in a courthouse that handles about 120,000 misdemeanor and felony arraignments a year. Basically I'm saying that I've seen a lot of people come through the doors for arraignments. In roughly 12 years, I've seen 2 individuals brought in with bullet holes in both the front and back of their heads....the bullet having traveled in between the skull and scalp for the entire ride. One was shot with .25ACP and the other with .32ACP. Both guys had the entrance wound in the upper forehead with the exit at the back of the head, about an inch or two above the hairline. I'm guessing they felt extremely lucky to be having bail afixed (as opposed to being in the morgue). I also know of one officer who was shot point blank in the forehead with a .38 Special who had the exact same thing happen. There are countless hospital arraignments done where the defendant is too screwed up to make it to the courthouse. I've heard of some of these persons also having similar experiences, but as I was not there to see this, I can only relate what I've been told.

5.57x28 I don't know!!!

So skulls are tougher then balistic kevlar?...

Some one alert the military, they sure are wasting a bunch of money on helmets for nothing.
Is it just me or does anyone else here understand the difference between "kevlar" penatration and "hard solid object" penatration?
I sure hope everyone else here doesn't think like 548...

You do realise a knife doing a 5fps will penatrate "balistic kevlar" too...

OK Gents and Ladies
I got the info I needed first hand up close and personal. I bought 6 Javelina heads from a local Taxidermist. From 7 yards the 195 hollow pt full penetration in the front and out the back not excessive wound cavity but good, about the size from a quarter but not as large as a half dollar consistently. The 196 red tip and 197 blue tip penetrated the front skull and turned the brain to mush, popping eyes. Also good damage/ fragment to the entry wound area, I don’t know if it is from back splash but defiantly good skull damage. Thanks everyone for your input. DAVID :lol: :p

huh?

"Is it just me or does anyone else here understand the difference between "kevlar" penatration and "hard solid object" penatration?"


Huh... You mean the current issue US helmet isn't a solid object?

I guess soldiers just have funny shaped heads to make their cloth kevlar beanie look that funny shape.

So maybe 197 is a better self defense round then?

I would say so 100% that little SOB will make a mess of what ever it hits but I dont think it would perform very well on car windshelds / doors it will just shread itself!!! and not get much more than small bits of it in the target IMO....

Since SS190 isn't available to us I use SS197 for my SD needs since it's designed to fragment/expand on impact (minus a CNS hit I want as much vascular damage as possible to enhance bleedout). My own informal and admittedly unscientific penetration/expansion tests w/water jugs shows slightly better overall depth of penetration w/the heavier SS197. The only significant difference is that SS195 seems to penetrate kevlar better than SS197 out of the FN FiveseveN pistol but both do a decent enough job out of the longer barrelled PS90.

OK 458 lets try this from another angle
I think that most of us or at least I am concerned about the guy breaking into my home to do really bad thing to my family or jacking my car, walking into a armed robbery or rape ya know self defense stuff not shooting at cops or troops or mercenary stuff. At least that my point of view self-defense. Shipwreck I agree that the 197 would be a great benefit as a defense carry round. And I think that I will alternate 2= 195, 1= 197 for the traditional Mozambique we’ll see how that goes. Maybe next weekend I’ll do it again if I have time and I’ll bring a camera to share the view. David one more thing for you PS90's out there check out this site http://magazineparts.com/ when i get mine I'm going for the rails :lol:
