Like many enthusiasts, I too have wondered just when a manufacturer was going to market a case that didn't have a belt on it for the public. Dakota and others started the trend and then the majors Win and Rem. They too though used the design of the 404 Jeffrey case as the base. It seemed to me obvious that the case could easily be made by removing the belt and keeping the base diameter the same as the rim, you could achieve greater powder volume. Our hunting calibers are sufficiently powerful and the hype for one compared to another is marketing only. The game couldn't tell the difference in getting hit with a .280 rem, 7x57 Mauser, 7mm-08, or 7x64 Brenneke, or 7mm mag at 50 yards further away. The need for the new cases are reduced pressures and thus the strain on weapons and more efficient powder burn. Increasing the base diameter of the case accomplishes this without a loss in velocity. I think that a case design like the .375 Ruger is just the beginning for a whole line up of new wildcats. Not that we need them, but the reloader like it for easy changes and campfire talk of having something unique. It would be a good case in .338, wouldn't it?
