Sidebar question: I was just given a 16-oz metal can of, "Du Pont Improved Military Rifle Powder, Number 3031." (Almost full red/white can) I suspect this is rather old, but I do not smell anything odd, although I don't know what I'm, "smelling for," anyway. Seems clean when sample poured on clean white paper; no color or rust; just nice graphite gray. Do I treat this the exact same as your subject here, "IMR 3031,?" I'm trying to judge condition/safety here. Haven't reloaded for a while; looks like I'll need to. Thinking for 30-30. Thanks
