new episode of box o' truth

[beerslurpy]

I love this guy's website. He just did tests on IIA and IIIA vests vs pistol and rifle. The M16 and AK both open up gigantic holes after penetrating, possibly a result of using clay instead of gelatin. The 5.56 made a whole big enough for a cat to live in.

linky

Check out the rest of his site too. Awesome info everywhere.

 

[KriegHund]

Ive sent his guy before, it is awsome.

4. If your adversery is wearing armor, don't depend on pistols or shotguns. Go for a rifle. As Clint Smith says, "The only purpose for a pistol is to fight your way back to the rifle you should have never laid down".

I dunno. After seeing the crater the 12ga slug left, I don't think too many people would have much fight left in them.

It also shows that while you may not be cut up by the bullet, you aren't going to be feeling too good.

Oh no?

Just kidding. I was wearing three vests!

 

[beerslurpy]

keep trying you will get it right lol darwin

Sweet Baby Vulcan!

*looks admiringly at the XM193* It doesn't look so beefy, but...wow.

Those "dents" in the clay is probably what shows up in people as severe bruising after being hit with body armor on.

 

[Bartholomew Roberts]

Clay retains the temporary cavity left by the bullet because it is inelastic - that is why you see large dents in the clay but a person doesn't suffer near as much trauma. In a person, the tissue is elastic and mostly water. It moves with the initial impact of the bullet but returns to its original position after the bullet has passed (kind of like dropping a stone in water).

Rounds that have a big temporary cavity look particularly impressive in clay, even when they don't always have a correspondingly large permanent cavity.

 

[KaceCoyote]

Go 7.62x39!

 

[BondageJaguar]

looking at the cavities, it would be interesting to have a vase made out of something like what the 5.56 or 7.62x36 left.

But wouldn't this result in blunt force truma to that portion of the body?? if that was a COM chest shot wouldn't it break ribs and or cause blunt truma to vital organs such as the heart or lungs???

That's just what I was thinking too. Anyone know for sure?

 

[Mr. X]

I believe the damage has to be such that it goes less than 3" into the body cavity when the vest is hit by the bullet, else it it considered to be potentially fatally trauma.

 

[Bartholomew Roberts]

I imagine it would.

My understanding from reading terminal ballistics literature is that different parts of the body have different elastic limits, if there is enough force that the temporary cavity exceeds the elastic limits of whatever that particular part is, then it creates permanent damage as that part ruptures or breaks.

 

[Jim Watson]

Well, you have to figure blunt trauma is better than a hole.

Second Chance used to publish pictures of their "saves" in the cop mags. A pistol calibre hit over a vest leaves about a three inch diameter bruise.

 

[walking arsenal]

interesting.

This brings up something that I have mentioned several times on this board.
When you see gunshot wounds for real, you can't believe the difference between a rifle and a handgun.
Handguns wounds are fairly common, but when you see someone that was shot with a rifle you are amazed.

 

[walking arsenal]

Amazed at what? That they survived it? Cause thats what i'd be.




Someone posted in the shotgun forum that a slug wont penetrate a vest but it would make the front touch the back.

I would put that on my list of things that would suck to have happen to you.

...amazed they even brought them to the hospital at all, versus the mourge?

look at that 2x4 ripped open.

 

[Correia]

We actually have quite a few folks on this board who have been shot in their armor.

The consensus is that it still really hurts.

If I recall correctly, George got knocked on his butt, and I believe the .45 cracked his sternum or something. Then I know a few guys who have shot themselves as part of a vest test. Once again, it hurts.

The only people I know who've been hit with rifles were hit in plates, and that wasn't to bad from what I understand. (comparitavely speaking!)

I don't know anybody off the top of my head who has taken a slug to the armor. I imagine that would hurt a whole bunch.

 

[OF]

Know any where the vest failed to pass that test??

Man, I just don't think that's something I could muster up the cojones to do...

[Cesiumsponge]

Quite a bit of blunt trauma from the 1oz rifled slug. ~1.9kJ for a 1oz slug at ~1200fp. Trying to crank through rusty equations and attempting to remember how to convert metric and standard...

I get something equivalent energy-wise being a 5lb brick being hurled at 134fps, or equivalent to catching one on your chest if you were laying down on a sidewalk and it fell off a 30 story (281ft) story building.

(assuming we ignore negligable air resistance on a tumbling object and terminal velocity, if its even reached and a free-fall time of ~4.2 seconds)

Ouch!

Wow, that takes some balls. Kinda like running your car into a wall to make sure the airbags work

No thanks. I'm in complete agreement wih GRD on this one.

 

[yesterdaysyouth]

i wanna go play with this guy...
