7mm rem ultra mag to 338 edge

[bsumoba]

found a good amount of 7mm rem ultra mag brass at the range (30-40 pieces) and was wondering if i can neck this up to 338 edge

Hey Brian, yes you can do that. The only difference of course will be that the neck thickness will be thinner using the 7mm vs. the 300's. I was thinking that the 7 ultra case was shorter, but not the case. The .338 ultra case is shorter than the 7 and 300...
