About this powder
H4831 is one of the most historically important reloading powders — derived from WWII surplus military powder, it became the standard for belted magnum rifles in the 1950s. Still excellent in 7mm Rem Mag, .300 Win Mag, and .264 Win Mag. The non-SC version has slightly longer grain length than H4831SC.
