I couldn't make that link work...I'm guessing it's the guy in the gravel pit shooting steel? A railway rail...and it turned his bullet directly around taking his ear protection off? I had a bullet go through my hair over my forehead...that was close too...just one of many. Ricochets I mean...
A fellow showed up at the range with steel falling plates shaped like the upper torso and head. They were used in pistol combat matches and had taken on a cupped appearance from repeated use. He was firing .38 midrange ammo and one bullet bounced back and struck him on the zipper of his fly. It took three of us to roll him over to see if there was a hole or blood in his groin area. None was evident but we did take him to the hospital. They had to cut off his pants since the zipper no longer worked. He was bruised pretty bad. Those targets went to the scrap dealer. Steel is dangerous target material. I notice that most are cupped out rather than in to divert the bullet safely. I'll stick with paper.
