how long

[sdmc530]

How long will powder and primers last in storage.
I store everything in a fire rated safe and I control the humidity pretty good?
I wanna stock up on some reloading components and want to get a mass stockpile but don't want it to go 'bad" before I use it.

thanks,,,,,

I'm certainly no expter at any of this, but I had the same question. From what I've been reading, primers will last many, many years if stored in a cool, dry place. I don't know about the powder, though.

Leave them in a cool dry place and they will last a long time. I actually loaded some shotgun shells with some older Winchester 209 primers I had. They all go bang still. I'll have to see how old they actually are.

A little advice about a cool,dry place. Do not make it too dry, static electricity can and will ignite primers. If they're in close proximity to powder at the time this would be considered Bad Ju-Ju.

Good advice, my safe is about 45% humidity that it what Champion Safes recommended so that what I keep everything at. I do keep them in the same safe I might have to rethink that though.

...take the powder OUT of your safe. If you have an expanding fire seal on the safe door, you just made a big ass bomb. less powder causes pressure as it burns
