sometimes gander mountain has cans of 7.62x39, dunno how much usually
whittakers down in kentucky has a bunch of cases for different popular calibers im sure they have some of that for a reasonable price and less sales tax in ky
Picked up a box of 357 at Strictly Shooting for $23.99. I was a Rajo's the day before and believe it or not they wanted $49.99 for a box of 50 (150 gr. JHP).
Great Outdoors in Jasper has .357 Magnum CCI Blazer Brass (Jacketed Hollow Point) for less than $20 for 50 rounds. Had at least a half dozen 1000 round cases.
They also have 9mm CCI Blazer Brass. My brother bought a 1000 round case a couple weeks ago for $180. Had 4 cases left at that time.
Also have cases of .380, 45, 38 special, and 44 mag I think.
Kieslers in clarksville has a pallet of 7.62x39. I didn't pay attention to the price though. They also have pallets of 9,40,45,223,308 and 50bmg. I think there was a couple other cals. also. I picked up 3000 9mm and 1000 40cal.
