[QUOTE="Pdvdh, post: 1980559, member: 4191"] I currently have some Hercules 2400 from the 1960s. Still use it. Still good. Provides the same MV per charge weight as the current Alliant 2400. It's 50+ years old. On the other hand, I stored some IMR4350 in a garage with big temperature variations, and it went acidic within about 10-15 years. Even though it was never opened. Go figure... Used it for fireforming wildcat casings. [/QUOTE]
