...From barrel end to invader. I’m not talking at shooting at a blank wall for no reason. The guy would be between you and any wall...
At close range, #6 shot would go through someone at home defense range, make about a 4” hole, and keep on going right through drywall. The 2X4 studs will stop it. But, not the drywall attached to it.
#6 goes through flesh and bone at close range like it’s not even there.
Don’t think so. The penetration of #6 on someone with a coat is about six inches. If the pellets should come out the back, the velocity would be not enough to penetrate drywall both sides (apartment to apartment) if the subject is in the center of a normal size room. I’ve done the walk at a simulation gun range; tested various rounds/calibers into different objects.
