Default how long can you store powder?

There is an auction coming up near me that has 8 pounds of IMR 4831 in a METAL can.
Advertised as never opened ???

When was the last time powder was sold in metal cans?

Don't know if I should get excited or not.

I had some 40 year old powder opened not stored in the best manor over that time. Tested it vs. new of the same type and it actually averaged a little higher FPS on the chrono. Seems to still be good. I'd say powder has a long shelf life.

I still have several cans of powder in the 1lb metal cans that have a sticker on them that says $15.95. I don't know how old they are but they're old and the powder is still fine. I've actually used some of it recently without any issues at all. The powder has been stored in a good place and hasn't been exposed to the elements so maybe that has helped in keeping the powder in good shape. No doubt powder has a long shelf life.

when powder became available again after obama took office I picked up some 760 and 4350 both of them are still shooting very well. So I would say over 10-12 years at least but I'm betting longer than that by a lot

Not certain anyone really cares but I did try to buy that 8 lbs of 4831.

I concluded people are crazy.

I looked up current retail price as if any retailer had any. I jump in the auction and bid up to retail price. Since it is in short supply I bid retail plus 15%. Now its just one other bidder. We bid back an forth until I bid retail plus 45%. Other guy out bids me, I quit. Another guy starts bidding. They go back and forth till the new guy bids retail plus 72%. New guy wins.

My inventory is currently about 100 rounds in five different calibers. If I run out I'll throw rocks before I'll pay that much.

Thanks again for the advise.

Unfortunately retail price is currently a useless number. I see powder being offered for sale at 5 to 10 times the retail price. The panic buying and the Federal Handout Program (stimulus checks) are making it tough for regular fellows.

I have lots of powder and primers that is over 30 years old. Still works fine, but would checl loads with chrono. If it has a acid smell it may not be good. The best way to store powder is in a load cartridge! Just my 1 cent.
