every time my father went to the gun shop he would look at the clearance rack and buy the cans of powder whether he used that type of powder or not I had 53 1 pound cans some with paper labels and a few with 79 cent price tags, I sold all of them to a collector. I have a few cans in perfect condition of Dupont black powder, full. looking for a home for those as I don't shoot black powder. I have 1 can of Dupont shotgun powder, paper label, and that is all it says no #'s or anything.I have a square metal Hercules 2400 can that is marked $3.04!
