Just remember that many ranges consider abandoned brass to be their property (they sell it to firms that reclaim and recast it for handloads), and some get pretty hard-headed about it, so if you use a brass-catcher or sweep your brass into a bag to take home you might just be required to prove it was all yours. That said I've never had a problem with guests collecting an empty of some "interesting" cartridge like a .44Mag or .357Sig, or with doing so myself, and I've never seen anyone who refills the cases they brought being required to sign their initials on every bullet they brought so it could be identified when leaving; generally as long as you take home the same amount of brass as you brought in you're fine.
