I'm a lefty so they hit me in the face. Let me throw a hot shell in your face before you take a shot and see if you care.
How does being a lefty change it. I'm surrounding by semi auto trap shooters at 2 clubs and I don't think I have ever see a shell eject at a angle enough to the side to be a head shot?
Being lefty Will not increase your hit count from ejected shells. If anything a right is more to get one down the back of the neck.
If ahotshells annoy you you don't want to shoot NRA/CMP service rifle
