I didn't see any listing for the "sc" on Hodgdon's site, I'm assuming to use H3831 data. More specifically, I'm looking for a load with the 7Rem mag and 168gr VLD.
4831 is one of my favorite powders. With my 300WM the 4831 shoots better than the 4831SC. I believe this is because the SC or short cut settles in the case a little better and allows for more empty case area. My speeds vari more with the exact same amout of regular or SC. I just thought i would mention it, because I noticed you were working with a 7mm Mag.
