I had this emailed to me by a friend.
This guy is extremly lucky. It seems he was using a 50cal Sniper rifle and shooting at a metal plate 100 yards away. It looks like the plate is securly fixed.
Anyway it only takes less then 2 seconds for him to fall over.
My other thought is what are the chances the bad guys have a metal plate in their head.
