I guess there are two distinct schools of thought. As somebody mentioned, though, if we are going to let ourselves get offended by brass coming our way on occasion, do we also acommodate the guy with the suppressor on his gun asking us to please not shoot if our gun is going to make that loud noise? I think part of the problem is not enough of us have been exposed to having been in a high power match, or in the military. In both, shooters are on a line, they are using semi-autos, and each man to the right often gets struck with hot brass. If you grew up around such, or were subjected to it, you know what to do. You button your shirt at the top, arrange your hat so that it keeps them off your head, and you man-up and take it. It is learning to DISREGARD it that make you a considerate shooter, not complaining about it. Think of it this way: you have been accepted to an elite shooting school, with some of the worlds best shooters/instructors there to teach you. Are you going to go up to them and whine about the guy on your left's brass hitting you while you are shooting? Most professionals I know would laugh at you.
