BillK,
Of course 9.3x72R works perfectly as Oskar said, but if it were my rifle, I would use original length 38-55 cases (2.125-2.130")from Starline. They are just a little bit short, but work fine, just seat the bullets "out" to the normal OAL. Bullets will likely be .318", but you might be able to use .320-.321" 32 Win. Spec. bullets. The new Flex Tips should be great. You may have to adjust rim diameter and/or thickness with 38-55 cases, but they are cheaper.
