#63 and #64 cover an important point. Hot brass is just one of a bunch of things that people concerned with self defense with a weapon ought to learn to ignore. A lot of people flinch because of the noise/gunshot; they have THAT to overcome. Brass from another weapon is not the ONLY hot brass you MIGHT encounter....you could get hot brass from your own weapon if standing next to a wall, etc. Learn to deal with it. To be fair, not all shooters at the range will be there to practice SD or even be interested in SD. The non "tactical" people ought to be tolerant of the fact that shooting is a MARTIAL art, and the endeavor of flinging hot lead, and hot brass, is always present, and that we do not live in a clinical world that we can control all side effects of such a martial art. I vote that we all EXPECT to be recipients of flying brass when near a semi-auto shooter at a range, and plot ourselves accordingly. Abstinence from shooting until we find a good brass-less spot, trading places, shooting on another day or a slower time (when one can have it one's way), etc. Even though I am extremely tolerant of others on this subject, I still like an empty range so that I can relax or push myself, depending on what type of shooting I want to do, without the interference of others. It doesn't always happen, but that is life.
