I am splitting my sides reading all the replies on this one.
Well, I shoot ARs, bolt actions, semi-auto pistols- amd I also shoot black powder (Baker rifle, Brown Bess musket) at the local ranges. Most people are just tickled pink to see a flintlock, that they don't seem to mind if I start shooting it, esp. when I offer to let others shoot.
As for the more modern guns, I have a home-made brass deflector and catcher made from a Vermont Teddy Bear Factory box- gets a lot of stares (who the hell is THIS guy??) , but NOBODY gets hot brass down their necks -or cleavage (sigh...)- from me. When I'm done, I close up the now-filled teddy bear box (looks like a little suitcase...), all the brass goes home with me, and I don't have to get down and bend around on my hands and knees searching for errant brass. Life is good for the Teddy Bear man....("Arms are for Hugging" :^D )
Also, something else to bear in mind: if and when the grabbers ever ban shooting entirely, you will miss hot brass......it will seem, in the end, to have been a minor annoyance compared to what happened with the "big picture".
