A guy came into a department the other day to ask a favor. He had a S&W 629 that he wanted to dispose of after a mishap at the range. He said there was a loud bang when he tested his new load and the gun smacked him in the forehead, leaving a nice gash. When the tweety birds cleared, this is what he saw.....
Dang. Just ...Dang.
This guy is lucky to be alive.
I'm thinking that there was a light load (perhaps no powder at all - just the primer went off) that lodged the preceding bullet in the barrel and the shooter didn't pay heed. Kaboom. Just look at the damage to the cylinder and the non-existant top strap.
