Hodgdon H4831SC Smokeless Powder 1 lb Canister Hodgdon H4831SC is an Extreme extruded powder and the exact ballistic copy of H4831, cut to a shorter "short cut" grain size for smoother flow through powder measures and more uniform charge weights. Overview The shorter, more compact kernels reduce the constant cutting of granules during metering and orient more compactly for better loading density, while sharing the temperature insensitivity and lot-to-lot uniformity of the Extreme Extruded line.
