I appreciate the input guys. This is certainly not need, but more of a gun nut itch that I want to scratch. I have lots of SAUM brass, and even more .308 brass, and necking either one up to .338 seems about as easy as falling off a log. Will either one do a better job than the 7 saum or 7-08 that I'm hunting with now? Probably not. I shot a young bull moose last week with a 120 tsx from the 7 saum that went 10 meters and tipped over.
