Hodgdon Powder offers one of the largest selections of quality smokeless propellants for rifle reloading. These powders are very popular with high power and long-range shooters, varmint hunters, and benchrest shooters.
Hodgdon's exclusive line of extruded rifle powders was developed to give shooters consistent performance load after load, in ever the most extreme heat and cold.
Ballistically, this is an exact copy of the H4831 with a shorter grain size. The shorter size allows H4831SC to flow through your powder measure and alleviate the constant cutting of granules.
