Ballistically, this Extreme
Extrude powder is the exact copy of H4831. Physically, it has a shorter
grain size, therefore, the designation SC or short cut. The shorter,
more compact kernels allow the powder to flow through the powder
measures more smoothly, helping to alleviate the constant cutting of
granules. With the smoother flow characteristics comes more uniform
charge weights, while the individual grains orient more compactly,
creating better loading density. Available in 1 lb. & 8 lb.
