    I am using H4831 with excellent results in some loads I am developing for my .300 Win Mag. However, when I ordered powder recently, I was shipped H4831 SC. Is there any difference to speak of between the performance of H4831 and the short cut version and is it substituted for H4831 weight for weight?

    H 4831 and H 4831 sc are supposed to have the same burn rate but as KcOpph said work up
    the loads anyway.

    The good thing about the H 4831 sc is that it goes through powder measures better.

    Same burn rate just a finer cut powder so you can fit more in a case due to a higher load density.
    From the Hodgdon web site....

    It is probably safe to say more big game has been taken with H4831 than any other powder. Bruce Hodgdon was the first supplier to introduce this popular burning rate in 1950. Since that time it has become a favorite for cartridges like the 270 Winchester, 25-06 Remington, 280 Remington and 300 Winchester Magnum. As an Extreme Extruded propellant it shares the fine quality of insensitivity to hot/cold temperatures, as well as superb uniformity from lot to lot.
    H4831SC - Ballistically, this Extreme Extruded 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. containers. Take the Extreme Tour

    I made the sc switch and won't go back. Uses same load was ale to go up slightly due to density.
