I've always done well at gun shows, but I know what I'm looking for and how much I am willing to pay. I've found it never hurts to haggle a bit. I've also stumbled on some great stuff I wasn't really looking for. One time it was 4 boxes of T/C .32 cal. Maxis, long discontinued, at a give-away price. I always enjoy looking at the oldies, both sporting and military, and it's a fun day out with a couple of friends, whether I buy or not.
