I was raised in Oklahoma,hunting pheasant,bob white quail,doves,ducks,geese an prairie chickens,rabbits,squirrels an white tailed deer.
Not once in all the years of hunting,did I or one of my hunting partners ever have to pull shot out
of ourselves.

Edit:It's the shooter's duty to know what he is shooting at and where his companions are. A shooting accident is always the fault of the shooter. Always.
