The indoor range that I go to occasionally will allow any handgun that you bring that is not a rifle round or metal piercing which excludes a lot of Encore shooters and BFR revolvers. .22 and 17 rimfire rifles are ok, as well as shotguns.
If you have a desire to rent one of their handguns you must buy ammo from them.
All I've ever fired there was cast. They finally got the exhaust system working better, so it's not nearly as stuffy as it was. Now if they'd improve the lighting......
And there's no problem collecting orphaned brass if the person that fired it doesn't want it. I keep a cheap nylon backpack in my ammo bag along with a small dustpan and have collected a LOT of brass.....
