Its only .004 thousandths longer to keep someone from sliding a 300 RUM cartridge in the
Big 7mm RUM and having a catastrophe. But that is insignificant in case capacity.
The 375 RUM on the other hand is the same size and after sizing you can turn the necks
down and have very uniform brass for the 300 or the 338 Edge.
In fact if I were going to build a 338 Edge the 375 RUM is the brass I would use to avoid
any neck thinning.
