You can even use a .375 Ultra-mag FL die as a body die for the .338 Edge. The .338 Edge is also known as the .338-300 Ultra-mag, and actually pre-dates the .338 Ultra-mag by a bit. The .338 Ultra is a bit shorter, mostly to make it easier to put it into a factory mag-box. Chances are that if the .300 and .338 Ultra-mags were released simultainously the Edge wouldn't exist at all. Shawn Carlock managed to get his company name associated with it early on, and it remains a cult-classic of a sort.
My reason for bringing it up is to illustrate what differences there can be in hitability with different cartridges. Some people seem to assume that rifles that have a bit of shoulder thump are automatically harder to shoot, like that is the only factor in the equation. That's not entirely true, it might take a more hardened shooter or a less recoil sensitive one, but its quite easy to find a "bigger" combination that is considerably easier to hit with. Hitting harder is just a bonus.
