I posted about this before but worth another...I guess.
Brother had my 38 'airweight' shooting JRN into some paper target having railroad ties for backstop. Don't remember the distance but thinkin it was about 5-7yds.
He fired and immediately grabbed his throat.
Projectile came straight back hitting him square in the adams-apple.
Luckily did not break the skin but sure put a nice whelp on him.
Surprisingly, the projectile was flattened a bit but still intact.
Upon further inspection of the railroad tie, they found a piece of flat steel embedded about 1/4" just under the wood surface.
Thanks OP for the reminder.
