Storing gunpowder/ammo?

[Lycanthrope]

I was thinking the other day that ive got a lot of gunpowder setting around in the original containers, mostly 8lb jugs, and since I dont use it very fast, I should explore better ways to store it. I ended up putting it in 1/2 gallon glass mason jars with desiccant packs and o2 absorber packs and vacuum sealing a bunch of it. I figure this should maximize storage/shelf life... Anyone else do something similar? How long, from your experience, is gunpowder good for before it starts to degrade? Its always kept in a cool, dark closet in my basement.

Also went a bit overboard buying and storing ammo recently... Sealed with silica and O2 packs.

That'll all last longer than you will with practically zero degradation.

By the way, can you guess what's in the O2 scavenger packs?

I don't do anything special with my powder or primers, i store them in containers that will keep water out unless submerged and powder is in original jugs. Up until a few years ago i was loading ammo with powder dad bought from sioux sporting goods. As far as long term ammo storage i have them in the MTM ammo cans and military surplus ammo cans if the seals were in good shape with dessicant packs in them. My .223 gets stored on stripper clips with spoons and in 30 round cardboard sleeves along with a few 30 round mags tossed in the can too. I like it this way because they stack nice, take up minimal extra space and when i want to go shoot prairie dogs or whatever i just grab a can and go and loading the mags is easy and fast.
