Hi Geno - WesB is correct, Hodgon is the one the makes the sc and the H4831 and H4831sc are identical in all aspects except kernel size. I have switched from H4831 to H4831sc in my 280 Rem and all my recipes stayed the same, it just meters better.
FYI, Berger has a ton of load data on hand as they are eventually going to put out a reloading manual for their bullets. If you email them which cartridge you are shooting the will email you back a spreedsheet with the load data they tested and their recommended loads. Good luck and enjoy retirement.
