There's an easy solution to this....don't crowd the shooter. There's nothing in the rules statign that everyone in the group has to be touchin elbows or anything. when someone else is shotng, I stand quietly, and far enough back so as not t be a distraction. Etiquette? I've yet to see anyone wth shell catcher for their semi (or pump, for that matter). Also never heard anyone ##### about flying shells.
