Cast my vote for the .38 Special revolver. Easy to reload, fun to shoot, and there's usually a lot of prime once-fired brass laying on the floor of the range if you're willing to stoop to that (pun intended). My Taurus model 82 cost me $340 new, and my reloading setup cost $299 including Lee 50th anniversary press kit, carbide dies, 1000 CCI primers, 1000 LSWC bullets, 1lb. of powder, and a reloading manual.
I've been reloading for about 4 months now, and the reloading equipment has already paid for itself at least twice, with the amount of shooting I do.
