Um, I don’t know if I buy that. Of course I’m not versed, and apparently maybe smaller calibers from certain guns wouldn’t be very effective, but....
...I do know of a man a friend of mine happened to see in a cemetery he visited. He ended up finding the man later (we’re graveyard nuts - he was doing some work with it that day), dead, his head in half and in pieces.
The man had shot himself (from the front) on top of a tomb and blown his head apart.
Hmmmmm
Thanks for a real life example. Much appreciated.
