When I was in Basic Training a kid who had been in military school was showing off twirling his M16
and doing manual of arms type stuff.
When he banged the buttstock on the sidewalk the rifle fired and blew a hole in his tshirt. He fainted and hit the ground. The drill sgt. came over and started feeling for an exit wound and then started yelling at him to get up
etc.
Turns out the rifle had been used at a military funeral and still had a blank in the chamber.
