Storage life

If primers are kept in an Air conditioned house and in the factory packaging how long should they be good for?

Same question for Powder. Unopened factory sealed jug(s) in A/C?

Thanks

Re: Storage life

Have had primers good for 5+ years and powder the same....

"how long should they be good for?"

I don't know yet. Oldest caps and powders I have are GI surplus from WWII, both work fine. I got both in the mid 60s; have no idea how they were stored before that. But they've spent most of their time since I got 'em in un-cooled and un-heated garages.

I have powder and primers from the 1970s that still work fine. I opened 2 cans of IMR powder last month, bought last year, that I had not opened. But they had a rust like brown powder in the cans on the powder.

I store my primers in the factory boxes inside 50 cal ammo cans.

Re: Storage life

Just finishing up using primers and some Win 748 that I started

loading back in the mid 70's. They have all gone bang.

They will last you a long time.

Re: Storage life

Thanks guys.
I found some FGMM210M primers in stock and ordered what should last me 2-3 years. Wanted to make sure i did not make another mistake.

Re: Storage life

Get primers in 5M cases. Store in 20MM ammo cans. Remove 1000 at a time and store these in 30 cal ammo can.

remove a box of 100 at a time, load and store ammo in ammo can.

this advice is from a Remington Primer Engineer I knew. humidity is the death of primers not only from misfires but erratic ignition problems.

Re: Storage life

had a some pull down 50 powder that went bad in about a years time. Had a real acrid smell and got a bit gooey. It was turned into fertilizer. Had some 296 powder that I used some 10 years ago and opened it up a month ago, loaded some up using the same data from 10 years ago and got the same FPS. Primers I think are more stable than powder so as long as they don't get contaminated I think decades.

Re: Storage life

I keep all my components in my basement/reloading room with a floor dehumidifier running at 38%-40% humidity.

I was told if you keep them in this kind of enviroment they will out last you in a lifetime.

Keeping it in a temperature stable environmet within the temp
range from manufacturer should provide a period surpassing your
lifetime of service.
