As has already been pointed out here, they are two entirely different powders and should not be interchanged. As to which is best suited to a measure, right now that'd be H4831SC. The SC designation indicates a shorter cut kernal, but the powder remains identical to (and interchangeable with) the original H4831. I'd suspect that IMR will introduce an SC version as well, but just haven't seen it yet.

Hope this helps,

Re: IMR VS Hogden 4831

While we're on the subject...does anyone know or understand the numerical designations on different powders? (i.e. xx4831, xx4350, xx7828)

Thanks! Just curious.

Re: IMR VS Hogden 4831

Hate to break this to all, but they're pretty random, and ther result of marketing decisions. May vary a bit from company to company, but that's the case for most that I'm familiar with. Hodgdon's "H380" came from Bruce Hodgdon's favorite load with that powder (GI surplus at that time), 38.0 grains in his 22-250. I understand that IMR3031 came from its ability in replacing cordite grain for grain in charge weight in the British service cartridge; hence we have IMR "303"1, or IMR 3031. There's more, but you get the idea.

Pretty convoluted, for the most part, and a good reason not to try to read too much into a designation.

H4831 seems to be the more popular powder, and the sc version meters very well. As demonstrated by the Quickload data, do not interchange the two.

With H 4831sc you might not get the highest speeds, but you will get your best accuracy and temperature consistency. My 300 WM shot to exactly the same aiming point at temperatures from 75 *F to 0*F with H 4831sc and F210.
H 4831 is preferred by the bench rest crowd.

IMR 4831 may get you higher speeds but I don't know what else.
I guess it depends. are you looking for MOA or MOE ? (Min. of Elk )
They're both kind of a pain to load because of the large grain size. Ball powder like Magnum sure goes through the powder measure more accurately.
