Are there any improved versions of the 7mm rum?
no really need of 7 RUM IMP 7 RUM is far a true over bore cartridge able to deliver velocity from 34 to 36 inch barrel with a lot carbon fooling , best and clver idea will be to make more efficient built on 338 RUM body lenght and longer neck ( run 300 RUM in 338 RUM and neck down ) you probaly get close velocity with less carbon fouling
for barrel under 32 inch 7 STW can do the best
