This is a copy/paste of part of one of my posts in another thread from a few months ago.
When I was shooting the match I had a 180 grain .40 bullet come right back at me after I shot a bowling pin. It hit a very sensitive area. I managed to finish the course of fire but I spent a good 20 seconds doubled over and swearing loudly. Ricochets can hit the best of us in the worst of places.
