Re: power question

Keep it cool and dry and it'll last a long time. I have some powder that's 30 years old that I'm not afraid to use. A chemist friend of mine said temperature above 90*F would start the break down process. The longer it stays hot at a time the more it breaks it down. Ever wonder why the military sells surplus? Or why ammunition manufacturers store there large lots in underground bunkers?

If it breaks down it may have an acrid odor (not to be confused with alcohol, ether, or acetone smell) and a reddish brown fume, according to Alliant.

Same here. Keep it cool and dry and it will last a long time.
