as far as a bullet doing a 180 is concerned, I've seen it, and done it. I was shooting a 380 with my father some number of years ago near scranton pa. we were side by side, shooting at some cans maybe 15 yds away. I had just finished when my dad kinda yelps. I asked what happened. he says I don't know, something hit me in the stomach. we look on the ground and there is the bullet.

this is a terrible thing though. imagine how gramp pop feels. I cannot imagine if that was my daughter.
