Originally the 8mm Mauser used a .318 dia bullet(I) then was changed to .323(S). Barrels were changed for this change(at least the ones in service at the time). The J(318) and JS(323) refers to the different bullet diameters. The JR is supposed to be for a rimmed case for single shots and drillings.
