Unfortunately for me, there is a semi-pro reloader in the area who has struck a deal with the two indoor ranges: he gets the brass, they get a slight additional discount to wholesale price on the ammo he produces and they sell. However, you can recover your own spent cases if you wish.
GunsAmerica has auctions of cases. "The Brass Man" at
http://www.brassmanbrass.com/ sells brass that at least sounds good. There is a pretty cheap supply available from
www.gibrass.com. There are ads in Shotgun News for .45 brass.
From looking around, I'd say $35/1000 is about the low end for mixed .45 ACP brass. Anyone seen a better deal?
