I was going to try a 180 gr Hornady SP with 42.0 to 44.0 grs. of Dupont 3031 (IMR 3031) in my .30.06 Sprg. It's not going very fast, butI know Hodgdon does not have 3031.

Does your olderP.O.Ackley manuals differentiae between Hodgdon and Dupont, or have a list of powders he is using? I have been compairing Ackley's loads to modern loads, so not to make a mistake. I think I will call RCBS and Sierra may be they can help. Thanks.
