Update: I poured out each pound of powder on a white sheet of desk blotter paper, looking for any red/rust dust. Four pounds of IMR4350 and three pounds of IMR3031 all clean. Whoopee!! I didn't check the Norma 200 or the half can of IMR4064, but will if I ever use it. I don't need the Green Dot or Blue Dot, Pyrodex, or any of the black powder, so will probably turn the smokeless into fertilizer. Can the same be done with black powder.
This day and time dumping powder just because you have no use for it isn't smart at all. Any of that can be used for multiple purposes if the shortage and need is there.
FWIW I'm still running a case of Dupont black from 64.
Bought a big keg of surplus ball from the late 60 or early 70s. Its all still running just fine.
I just can't envision folks throwing away good powder. Primers or bullets. Heck I'd use 270 if I was forced to. And even with game kings if thats all I had.
