I have a small set-up where I can test ammo fired into different materials.
Being interested in light calibers I today tested CCI .22LR Stinger, rapid fired at a distance of 10yds from a Walther P22 short barrel pistol.
My target was fixed to my frame, with three sheets of 1/2" drywall and two sheets of 1/2" hardibacker (cement tile board) as the board.
That's 2 1/2" of cement boards that the round had to slow it down before it can exit and carry on into the cinder blocks behind.
I checked the target after the first round and again after the tenth.
The first round dented the back of the fifth board, by the seventh round I was shooting straight through the 2 1/2" thick target.
I'm not advocating carrying a .22LR, I haven't tested the round into ballistic gel yet and won't be packing the Walther.
But it does make me think about what it would do to a side of ham.
