This is a good post to remind people shooting and around shooters to wear eye protection. I was at a friend's range a couple of years ago. A Chapui double rifle [big] was being sighted in at the hanging cast iron or steel swinging targets at 50 yards. I was standing behind the shooter to the left as he shot. Schrapnel from the shot came directly back at us and one piece pierced my canvas pants, drawing blood from a skin cut beneath the material. I am not sure of the physics of this, but it happened.
