Mine are pretty minor in comparison with a lot of these, but the most painful was earlier this year at the range, I was fire forming some brass in my 338-06 AI, and a guy comes along and sets up a position or two to the left of me. He breaks out a semi auto .22 and is happily blasting away. I'm getting pelted with hot brass, and getting a little upset about it. I turn to say something to him about it, and I literally catch a piece of hot brass with my lips. I didn't think too much about it, since it was only .22, I mean what harm could it do? I've been hit with hot .223 brass and had it go down my shirt, which sucks in it's own right. When I go to leave, I go use the rest room, look in the mirror and both of my lips are all blistered up. I go home and my wife makes me pop the blisters. It takes about a week for my lips to heal, every time I eat something with any sort of salt or acidity in it, it burns like fire. All from a stupid piece of .22 LR brass.
