I just bought a Win Mod 70 in 300WSM. It rocks! I think it will outlast the Remington SAUM because its just a little bit longer and has more case capacity.
I could quote you the numbers, but, suffice to say, it is just about identical to the 300 win mag. IMHO, the 300 win mag is now obsolete!
Yes, a cartridge the same as a win mag, in a short action!:beer:
