Handgun shooting through 2 sheet rocks and a 2X4? NO WAY!!

[braindead0]

Just yesterday I shot through 3+ inches of PT pine.. was a 2x12 laid flat on a sawhorses, 125gr XTP moving at around 1800fps.

Nice clean hole, didn't measure it but it entered at probably (just a guess) a 20degree angle.

This also is the reason that my ready gun in the house (3 kids and wifey) is a shotgun.

Ever try shooting the shottie at a wall?

Anything more than a .410 out of a pistol and you'll punch through with no problem, I promise. Not that a shotgun isn't a suitable home-defense weapon for many situations, but don't assume that it is less likely than a pistol to go through a wall at distances you will encounter in most homes.

Been there, done that, got the t-shirt.

Buddy was rehabbing, made some wall sections outta 2x4s and sheetrock.

EVERYTHING centerfire went through (we had .380 and up).

That included shots at studs.

Only thing that was reliably stopped by the 2nd piece of sheetrock was #6 and smaller shot.

From how far?

 

[bogie]

Oh heck... I dunno - a no-choke shotgun pattern made about a 6" hole in piece #1, but dimpled the other side. I'd guess considerably under 7 yards - we weren't all that scientific once "blastin' mode" kicked on...

My Father-in-law told me a story about .45 ACP penetration.

He was stationed with the occupation forces in Germany right after WW2. He was assigned to an MP detachment with the AAF. It seems that there was a thriving black market in the area, and one of the favored items of the thieves was the Jeep. One day some of his MPs spotted a guy as he was in the process of stealing a jeep. This jeep happened to have a steel hard top. The MPs gave chase, and the thief refused to stop, so one of the MPs pulled out his 1911 and fired one shot. The thief locked up the brakes and exited the jeep screaming. He was sure that he was a dead man. The bullet had made it through the back of the hard top, but was slowed down enough that it hit the German National in the back of the neck and then fell to the floor behind the seat. It did not even break the skin!

Has anyone set up a chronygraph on the other side of the wall to see what the velocity is of a wallboard ladden 9mm hollowpoint?

A post wall, ballistic gelatin block test might be in order too.

Just make sure its your buddys machine.

I had one and only one AD. It was a Rossi .38 spl loaded with CCI 158 hp's. I was lowering the hammer and it slipped (thankfully pointed in a safe direction). The bullet went through the 5/8" plywood floor, diagonally through the 2X10 floor joist and took a good chunk out of a cement block in the basement. I found most of the projectile, but not all of it. I think most centerfire projectiles would have little problem going through a 2X4 and 1" of drywall. Just my .02.

Bogie:

Did you shoot any rifle rounds?

I understand from a LEO and trainer there was an article published where .223 soft point (varmit rounds) did not penetrate the second sheet of sheetrock (i.e. the round fired did not exit the room in which it was fired).

I have unable to find this publication and have consulted experts including Sanow and Fackler without success.

The article was alledgedly a comparison of 9mm fmj from a subgun vs. .223 rem from a M-4 style entry weapon. The article was to have appeared in the LEO press.

thanks,

Doc

What is going to happen if some lurking moron reads that and says he's really, really convinced and then he goes out and finds some other moron to shoot at him through a flimsy wall setup?

Then, thanks be to God, the herd would be one imbecile thinner.

 

[Croyance]

Why does your friend even think that sheet rock would be a factor, except to plug the hollow of a hollowpoint?
Any guy who has been at loss for words can tell you how easily a hand goes through sheet rock.

 

[gun-fucious]

the 9mm vs 5.56 data is on olympic arms site:
http://www.olyarms.com/223pen.html

the major point is the 5.56 is less lethal on exiting a wall due to the velocity dropping
