My brother was hunting in PENN rifle season many years ago and heard a shot close by. He heard a guy cursing and walked over to see what was going on. The guy had knocked a pretty good size buck down and it was still alive and he had a spent shell stuck in the chamber. My brother offered him his pocket knife and he got the shell out, chambered another round and finished the deer off. He said the whole incident lasted less than a minute if that, and my brother said it never occurred to him to offer to let him use his gun to finish the deer off. it turned out the guy knew my dad and dropped off a case of beer later that night for my brother.
