I don't know where you live but homes are not made of drywall here. Of course it is used, there is also insulation, plywood, 2x material and then whatever is on the outside, more wood and or brick.

I guarantee you a 5.56 round isn't coming out the other side of that and if it does you can catch it with your hand.

A 9mm is effective to about 100 yds. After that taint could punch harder if he uses his purse arm.

Florida man burns pet bunny that bit him

I got a pellet rifle that will go through 5 sheets of drywall.

How about 1 layer of drywall, a sheet of plywood, and a layer of brick? Will it go through that?

how thick is the plywood?

the one my wife keeps in the drawer is at least 10 inches.

The answer is no

of course it is.
just curious how thick is the plywood.

5/8 I'd think, maybe 1/2
