P-245, go to American Shooting Sports in Katy, TX and ask them about it. It's part of their policy. While it's a basically nice place, it's huge and they have a bunch of "rangemasters" roaming the line, but these guys don't have the time to watch Joe Brass-Chaser leaning over the firing line to snag that last case... so their policy is that unless it's REALLY, REALLY your brass, AND you shag it very safely, it's better to just leave it. So I use Blazers when I shoot handguns there, and now I know I can shoot Barnaul .223 through my AR without any problems, so American Shooting Sports can collect up my empty steel cases and recycle them for me.
And to be frank, sometimes it gets distracting to me when I'm shooting and I consider where my empties are going. And somebody else crawling all over the place looking for a couple of his errant 9mm cases while I'm trying to shoot is really obnoxious.
Here in San Antoino, I go to the Bullet Hole range, and they don't care WHOSE brass you pick up, just as long as nobody complains. But it's a smaller range with a different sort of clientele.
