I' ll be damned! The NRA reloading manuals that I use for teaching

as fertilizer to destroy it. I won't teach that anymore!

Tom, sun (UV), moisture, and bacteria will decompose both single-based
and double-based powders. Both nitrocelluose and nitroglycerine will
decompose under those conditions, as will nitroguanadine -- the 'triple-
based' third component.

They just make lousy fertilizer, tending to significantly lower the soil
pH to levels dangerous for many plants. 'Might work on gardinias or
camillias...

At least I, or anybody I know has had powder to destroy. It will last
forever (almost) if kept sealed and cool. For it to go skunky would
mean improper storage or it's VERY old. I go through it too fast to
worry about it, but I never have too much laying around, I've only got
about 9 lbs in the cabinet. When I DO have a good quantity, I tend to
burn it faster.
