RE: Power Level Ammo
I think maybe because the 7mm RUM is almost dead you're not finding it.....
reason you're finding 300 RUM ammo is because its popular and a successful new round.
I think this power level ammo has been around for a while now too, at least a year if not since the RUM inception.
Also might point out why do we need power level ammo? I guess it gives new meaning to the 1 rifle concept, but really, if you have a .300 RUM,I want full power from every round, not power level, 1, 2, and 3. If I want less power I'll just use my .270.....
