No guesses please.
I need a 100% sure answer.
Last year, I bought out a friend's reloading supplies. There are two ea. 3/4 cans full of Unique powder. One is Hercules in the old style cardboard can and the other is Alliant and in the newer plastic can . I think that they are probably the same, but I'm not a big pistol /shotgun guy and not 100% sure. Anyone know?
