At the risk of turning this into a gun thread, I've had pretty good luck getting some decent prices through ammo seek. A huge variable in buying ammo by mail is shipping, and ammo seek allows you to filter by shipping cost ratings. Outdoor Limited, who lists on Ammo Seek, always has free shipping if you spend $200, so if you were spend that much you could get 45 ACP for about 38 cents a round, as an example. Found a local place, Shaw Armament, advertising there and I dropped by and picked up 38's for 40 cents a round and 357's for 50 cents. That's the best I've seen in a while. These are the cheaper lines, Magtech and Sellier & Bellot and such, but I always filter for brass only, new not reman.
