You might look at chambering for a 300WM case but to 7mm. The 7mmRM is a little shorter to the shoulder than a 300WM case. I am not for sure why the 7mm RemM case is a little shorter to the shoulder.I thought about I've run the 300 and 338rum for a couple of years now. And I think I'm looking for something that doesn't eat up as much powder.
