An odd one that my dad swears up and down happened to him while we were hunting was that we jumped a moose and he let fly with his 30-06 pump with the old dominion round nose bullets.
He had fired three shots at that Bull Moose while it was running through the brush.
One of the shots had hit the rear hip and the bullet head turned around in the hip socket and came back out about an inch apart from the entry. Or so he claims.
There was four holes in the hide and none had exited the far side.
We found 2 bullets but he swear up and down that he only fires 3 shots with four holes in it. I was just young at the time I am a little hazy on the details. Crazy of it did happen!!
