I am aware thatIMRPowders were once Dupont Powders. Does anybody have a list of Dupont Powders, or did IMR keep all the original powder names? Thanks in advance.

It seems to me that the designations are all still the same as they were-I don't believe IMR has added any new powders, and all the old ones are still the same number.

IMR is now owned by Hodgdon... all of the numbers have remained the same and the IMR designation is still in place
Rootsy is right,but remember when and if you reload and i assume you do,just because Hodgons owns IMR and the numbers haven,t changed, DON,T get mixed up with H numbers and IMR numbers. Like 430,4831 as examples. vangunsmith

you are absolutely correct.. IMR 4831 and H4831, for example ARE NOT interchangable. Also be careful.. Hodgdon IS putting some of the IMR powders in the round plastic containers... so read the label carefully before purchase. IMR 4350, the last lb i bought was in a plastic bottle vs the metal can...

I realize IMR and Hdogdon share powder numbers. I found a 1965 P.O Ackley book and it calls for Dupont Powders. Thanks.
I have ackley books also,and they have many diferent great loads in them.What calibers are you so interested in reloading that have to have DUPONT powder if i might ask? vangunsmith
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.

I wouldnt use IMR 3031 for a 180 grain pill in a '06. I would consider either H4350, IMR 4350, H4831, or IMR 4831. I consider IMR 3031 to be a tad fast for a 180 grain bullet.
