hillmouse Posted February 13, 2011 Report Share Posted February 13, 2011 Due to the lack of foxes here my powder supply has sat unopened for several years as it simply has not been worth the effort loading the few rounds required. So........... How long does a tub of opened rifle powder last?? There is nearly £400 worth of opened tubs but with the sealing caps in and the tops screwed on, stored in a cool dark, dry room. It looks fine, nice dark grey colour, no crusting and no acrid small. Bin it or risk it? Quote Link to comment Share on other sites More sharing options...
fortune82 Posted February 13, 2011 Report Share Posted February 13, 2011 Im no expert but reckon it will be fine. I was on a world war 1 battlefield in the summer and found an unfired strip of .303 rounds. The cases disintegrated in my hands to reveal the propellant. I poured it on the ground and lit it and it still burned well after 90 odd years in the ground! Quote Link to comment Share on other sites More sharing options...
PAULT Posted February 13, 2011 Report Share Posted February 13, 2011 I just finished a tub of n160 that was opened in 1997 Quote Link to comment Share on other sites More sharing options...
garyb Posted February 13, 2011 Report Share Posted February 13, 2011 Why on earth do you have £400's worth of powder? By yesterdays prices thats a hell of a lot! Anyway... providing it still smells a bit like weed killer, I think it would be fine - But why don't you load a few test rounds and fire them ?

Vince Green Posted February 15, 2011 Report Share Posted February 15, 2011 I am just finishing off a tin of Nobel rifle powder I was given when someone died, 1978 and still works fine. Quote Link to comment Share on other sites More sharing options...
Vipa Posted February 15, 2011 Report Share Posted February 15, 2011 The quoted shelf life is 50 years plus if stored under optimal conditions, i.e. dry and cool and dark. a couple of decades won't cause any issues even if storred under average household conditions..... as long as you have not let it get damp.

Alycidon Posted February 15, 2011 Report Share Posted February 15, 2011 If kept in the dark and cool life is pretty well unlimited. What makes and types is it?, you might be able to sell some here. A Quote Link to comment Share on other sites More sharing options...
