That is SSC which stands for Super Short Cut. IMR-7828 is a long grain extruded powder, and the SSC is easier to get through a powder measure and probably causes less space issues in a cartridge case to allow more consistent powder charges.

It is a great, large capacity powder for magnum cartridges…
