Too bad you don't have a Dumhams sporting goods store. On Sunday, PMP, a South African ammo, boxer primed, reloadable case, in soft points, $5.95/box of 20...in 243,308,30-06,303 british. They also have some 7.62x54, and other surplus ammo at cheap prices.
I would have stocked up more, but I can reload cheaper than that, that's something you should be thinking about. Lee makes dies for your Russian round, and Remington and Winchester makes cases. A nice single stage press, a powder measure, some case lube, a lee hand primer tool, and some powder and primers, and you might never run out of ammo...
