Hodgdon's H4831SC rifle powder is an extreme extruded powder that is the exact ballistic copy of H4831. Physically, it has a shorter grain size which earned it the "SC" designation for "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. Our customers reside all across the country and are governed by numerous federal, state, county, city, and municipality regulations for these types of products. Please consult your area's laws and regulations governing this product and its use. | Hodgdon H4831SC Smokeless Rifle Powder | Size 1 lb
