To be clear H4831sc is AR2213sc, just in a different bottle although lots may differ. H4831, originally a surplus powder, later made by Nobels and now by ADI as AR2213H. There were some significant variations in speed The later is not available to the public. AR2213 was made by ADI from about 1986 to just before 2000 and is now obsolete. AR2213 is a little faster than AR2213sc. Dupont made the original IMR4831 that was sold by Hodgdons as surplus as 4831. Current production is faster than any of the others. Data for AR2213 is obsolete and should not be used. Some of it is very hot.
