Oday450Mike - the Hodgdon powder is the same just cut smaller to flow better in measures. Here's a quote from their site:
quote:
H4831SC - 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. containers.

FjoldH4831 and H4831SC perform identically in my 7 mag and 300 WSM with no more variation than different lots of the same powder would show.

One other thing to note. The SCs will respond to a drop tube better than the LCs. A drop tube will get about a 5% improvement in capacity using something like H4831SC whereas original H4831 or IMR 4831 have little to no responce. In some instances, this can determine whether you get enough powder in the case to do what you want to do. 404J comes to mind where the SC was an advantage.
