[QUOTE="Kennibear, post: 1247583, member: 51650"] Heat kills powder faster than moisture. Some double based powders like Unique are essentially water proof. One of the first batches of Laflin & Rand's (then Hercules, then Alliant) Unique has been kept in a jar of water for more than 100 years and it still tests fine. Most ball powder has some nitroglycerin but not 30% like Unique. I agree with the silica gel storage however, even though a tightly sealed factory container is pretty moisture proof. A cool basement in an air conditioned house is probably best. I had some 3031 go bad but I got it in a sporting goods store closing and God knows how long they had it before I bought it. The price tag said $3.15 full price. KB [/QUOTE]
