I had, at one time, a 6 pound red 'drum' (can) of American Deadshot powder many years ago. The can looked just like that green one. The powder was clean, hard shiny grains of powder, about 2F in size. No dust. It was the best powder I had shot up until that time, about 1975. There was only 2 pounds left in the can when I 'got' it. Very accurate and quite clean burning as well. I used it in a slug barrel by Bauska I bought the barrel from Les (Kalispel) in April or May of that same year.
Mine went by the board at some time or other.
