Here's a pic of the stuff I was shooting at when I got hit by that .45 ACP one. This isn't the exact plate- the "offending" block was a similar one, but I eventually blew that block to smithereens with a .308 rifle.
The two JHPs stuck in it are .40 S+W Speer Gold dot 165 grainers. They actually did mushroom quite a bit.
The pockmark below and to the right is from a 230 gr JHP, IIRC, I think it was a Golden Sabre. Theres a similar hit below it and to the right.
The little hole above the first pockmark is a 7.62 x 39 exit wound of sorts, if you hit it at the right angle, it would just drill right through it.
The "blackish" holes to the bottom and the right are from 7mm-30 Waters, AKA "730 Waters". The bullets must've been JSPs or something like that, a lot of lead was shed off on its way through.
The pile of crap to the left is a few different hits from 730 waters, 7.62 x 39, and something else maybe.
It is too bad the other block didn't survive. The other block had some fairly interesting damage, including a hit from a .35 Remington. That round might be old, but it's no joke.
