I was able to buy for 30 bucks an 8lb tin of DuPont IMR-4227 still had the metal seals on the tin. Tin is white whit read and black lettering, Powder smells really good and no rust in it. Looks like the day they put it in.

My question is Hodgdon H4227 and IMR-4227, are these powders compatible?

I see loads for both in my reloading manuals Lyman has a lot for the IMR-4227 for hand guns but my Lee Modern reloading has H4227.

Just want to make sure I do the right things.

thank you
