it had better be a thick BRICK house... lol! else the 7.62 will cut through the brickbats like a hot knife through butter and still light up the neighbor's lives. i've done tests personally and actually shot entirely through a "trashed" car's body---in one side and out the other---with the 7.62 round---which continued on into the gully towards parts unknown "after" exiting the wrecked/shotup auto.
i tried the same thing with the standard .223 (M-16) bullet and was lucky to have sheet metal penetration on just one side of the auto.
as for my own personal protection, i keep several weapons around and ready...mostly some shotguns, one of my little M-1 carbines with softnose bullets and a thirty round mag... and a couple of pistols... a S&W revolver and a Colt .45 auto. any of which could easily discourage a house invader... that is IF they get past my outside dog...old Captain Jack. which ain't too likely. they'd have to kill him to get past him and he would die hard...and loudly...which would completely alert anyone at home to arm themselves asap.
i live wayyyy off the road you see... wayyy out in the sticks... too far for immediate police protection. so long ago, my wife and i thought about such things and have tried to prepare for it...just in case.
Captain Jack is the first line of defense, my two inside dogs are the second... by then, it'd take a squad of heavily armed commandos to go any further. lol!
and even they would surely catch some heat.
some may think it foolish, but we think it being smart.
