I still have the tag end of the keg of Unique purchased in 1967, just before I was told it would be nice to spend some time in VN. Only difference in the newer lots is they have made it cleaner burning. I haven't loaded shotgun in 30+ years, and there always seem to be new powders that would be fun to try in pistol. Lots of partial cans here. At least 3 can colors of 4759, Dupont bulk shotgun, WWii 4831, Norma 870, the list goes on.
