Not just "hard core shooters or survivalists" go to appleseeds, right? While some of us might consider it good training to be able to nail targets with hot brass flying in our faces, others might not appreciate that. Specifically shooting newbies or people that are on the fence about shooting and going to an appleseed might not enjoy getting hit with hot brass. I think we should make their experience enjoyable, so that they will come back again.
There are people of all different levels and places in their lives. We want to attract and retain as many shooters as possible. I like the idea of being able to separate and space out the lines according to shooter preference if possible for people that don't appreciate getting hit with hot brass. I've been to one appleseed and endured hot brass from a Ruger 10/22 on my neck. It left a scar for quite a while and it hurt. If that happened to someone else they might not want to come back. My main point is that we are trying to recruit and retain people to the sport, and not everybody is in the same place mentally with regard to the 2nd ammendment and shooting. That's my 2 cents.
