I personally dont see a difference in a 7mmSAUM and a 7mm rem mag. I mean book data says around 3100 fps for the SAUM, Thats easily achievable in a Rem mag. Plus the only advantage is the short action, but Ive heard of feeding problems with that short fat case (just what Ive heard no real data).
Actually, since it holds more powder, the 7mm Rem. Mag. can be loaded to beat the 7 SAUM, just as the regular .300 Win. Mag. will beat the short .30's as well.......
Laramie, due to the short case and short neck on this cartridge, it would be better to use bullets no heavier than perhaps 150 grains, if you don't want to have the bullet taking up some of the space where powder should be. What is it about 140 grain bullets that you don't like?
If you useNosler Partition, Barnes X, or other tough, controlled-expansion bullets, the 140's are adequate for game up to elk when used in the 7mm SAUM.
