Drywall penetration

15 sheets for 5.56mm ball ammo, but 'only'
14 sheets for Hornady Critical Defense 9mm, and
14 sheets for 12 gauge buckshot...

Seems like whatever you shoot inside a house, you'd better mind your environment and who is where.

I'd like to see the same study using a few other loads though.

Good thing there's whole lot of other stuff in those walls. Not to say it you couldn't shoot through the entire house, but it would be unlikely.
I'd like to see what would happen with plaster walls, as well as other calibers.

I had an ins. claim a few years ago that involved a shooting. Guy chasing his wife around the house with a .45 ACP. I don't remenber the total round count, but he's finally cornered her in the kitchen. Then shot himself. The only bullet that made it outside was one that went through a window and lodged in a deck board. Most had struck a stud, wiring, plumbing on the way through. There was one bullet that hit an exterior wall. Went through 1/2 drywall, 3 1/2" fiberglass ins. and stuck in the 1/2 OSB under the vinyl siding. What I don't know if it had hit something or someone ( no blood in that room though) before it hit the wall.

My point is, you can't count on anything once that trigger is pulled in a situation like that.

By the way, not trying to be argumentative, just throwing out other possibilities. Seems like everyone is a little on edge lately.

Yeah. I think the main thing is that some folks out there assume that all rifles over-penetrate, but that shotguns and handguns somehow never do.

They are forgetting about bullet construction; it's no less critical in home-defense scenarios than in hunting scenarios.

Generally big chunks of hard metal going at modest speeds penetrate lots of stuff, no matter what they are fired from. The folks who obsess about what gun is used are missing the point.

Some years back I made some “walls” of sheet rock separated by 2x4’s. I shot them with a 405 gr 45/70. I had 8 sections. The rounds went through them and then through an old washing machine.

I like my neighbors so I still use my 20 ga for household use.

Brick house, thick plaster walls.

I think it was box of truth that showed 556 penetrated less than 9ball

Sounds like a good reason to teach and train your family to hit the deck if shooting starts. Stay lower than chest height and most of the civilian rounds will go over you. Civilians tend to shoot chest high or more. Still, bullets can and do occasionally go where they were not intended to go. Besides, if you are low, shooting slightly upward is easy.

WELL, doesn't it go back to the rules? KNOW WHERE THE BULLET WILL STOP BEFORE SENDING IT.

isn't that our responsibility? I walk the house and grounds looking for the safest fields of fire downrange from the bad actor [see what i did there?]

Good one, Grizz!
