This is amazing. Willie, the guy shooting the AR-50 is a friend of mine. The target, a 1" steel plate was 100 yards away. You can hear the ping of the hit, then the bullet comes back and hits him in the head. http://www.digg.com/videos/sports/Man_shoots_self_in_head_with_the_ricochet_from_a_50_rifle Willie is okay, and obviously very lucky. The bullet grazed his temple. Can anyone calculate the velocity?
