Some reloading equipment I bought recently came with 3 tubs of N-140, 2 are opened and dated 2006, the other is unopened and dated 2009. The website says they have a minimum shelf life of 10 years,does anyone here have a view on whether it is still ok to use,I'm reloading 6mmbr
Thanks

My Vit 160 for my 6.5x55 is dated 2003 and it's perfectly fine and my Vit 140 for my 6mmBR is 2009 and it'll absolutely fine as well.
Recently finished my tin of Nobel Rifle #1 Powder. Excellent stuff.
Using Nobel Pistol Powder #3 for 0.357 U/L. Again a clean burning powder.
Almost indefinite shelf life if stored correctly.

Just finished a tub with an ‘88 date on it. Stored correctly, you have nothing to worry about.
The powder should be fine if store correctly. I have used powder donated to me that was years old with no problems. If in doubt, make a small batch up to try first.
I've used plenty of powder over 10 yrs old. Never had a problem. How would you tell if its off?
Great comments and thanks to the OP for starting this thread as I've a few tubs of various powders that have not being used for a few years since me buying them due to my shooting changing. What is 'proper/correct' storage?
How suitable would a cool, dry, unused room in our house be?
The UK climate is probably about as good as it gets for power storage. No extreme heat or humidity.
As long as its not stored in the loft the powder would keep for a very long time.
I keep mine in a blackpowder storage box as I don't use black anymore and its somewhere convenient to keep it.
I've a tin of Nobel no.80 from 1983 that seems absolutely fine. No idea what I'll do with it I don't reload for shotgun.
The 10 years come from the single temperature NATO AOP 48 stabilizer depletion test, this is simply a pass or fail criteria, a pass giving 10 years storage in temps of <25'C. In reality the shelf life will be far longer!
So what about the 50 year old mil-surp ammo that people are still using.. that powder is obvioulsy still ok..
kirkleese guns ( Huddersfield) are still selling 1998 /99 powder @ £75-kg & assure us it perfect .....
