To those that have used both powders in the same load: Have you had to adjust weight when going from one to the other?

Re: burning rate of H4831 vs. H4831SC
I do not use SC, but it's nice to know it's there, if I desired a compressed load, or anything approaching 100% fill. But, the same rule applies to switching between SC or the regular H4831 or IMR4831, you need to back off a little bit, just in case one lot is significantly different. This is not a huge concern. In my experience, I see very little difference from lot to lot, but you have to check it out anyway. It normally involved a few tenths of a grain, but on the other hand I see a significant difference between H4831 and IMR4831. In a particular cartridge, I max out about 43.X grains of IMR, but can go up to 47.X in the Hodgdon brand. Accuracy is about the same but the velocity is significantly higher with H4831. BB

They are ballistically the same, one is just cut in half and the other isn't.
I've used both in my 338LM loads until I bought an 8# jug of 'sc' and I've still got two pounds of that. I have some long cut as well.
The shorter kernels meter better through my Dillon measure and my ChargeMaster 1500.

I have used the same load weight with both in a .270 Winchester with good results.
Good luck

Opposite of BB. I use H4831SC only. I think it meters just a bit better and has better density in heavy charges. That means I can pack more into the 260 Remington case.

Re: burning rate of H4831 vs. H4831SC
If you mean I don't use SC and you do, I follow you. My reason is that I have been using H4831 since way before they came out with SC and the metering is not a big deal for me, and being an old fart, I continue to use the plain vanilla version. If I had a load that required more powder, and it wouldn't fit, I would sure as heck switch to SC. Until then, we're opposite. BB
