In my load data, and the loading data I have found online there seems to be no distinction between H4831 and H4831sc. Are loads listed for H4831 always pefectly adequate to substitute H4831sc in it's place. With the increased surface area created by a short cut I thought it might affect burn rates
H 4831 and H4831sc

According to the information on the hodgdon site the 2 are interchangeable.H4831® & H4831SC®
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

I have actually mixed the two in some hand loads. I had the same question a few years back when I needed more 4831. All I could find was the SC. I was told, and read, that they are the same interchangeable...so, I used my remaining bit of 4831 with the SC. No problems.

They are both the same powder. One is cut "shorter" than the other.
When using the powder by weight use the same measurements. If loading by volume (ie: a powder throw) there will be a slight differance between the 2 when weighed.
Most guys who throw powder will still weigh their charges and trickle to the desired weight.

You Nailed it.
SC works better in the 260 and 284 cases as the loads tend to be compressed with the longer kernels.
Because H4831SC is smaller it will not fill the case quite as much as the regular H4831 and therefore you will get slightly lower pressure from the same weight charge. Everything else is identical. You can use load data from H4831 for H4831sc but should do load development for each seperately.
Good luck
