Super User NHBull Posted November 14, 2020 Super User Posted November 14, 2020 regardless of what you do, buy a bag of silica kitty litter ( dustless). It will absorb moisture when it relative humidity gets to 60%. Museums use a form of it and cigar collectors have been using it to regulate RH since it was made. 3 Quote

Super User Way2slow Posted November 14, 2020 Super User Posted November 14, 2020 What little I keep loaded, I store in mil surplus 50 cal ammo cans with desiccant bags. Since I reload, I don't need to store a lot of loaded ammo. Powder stores nicely in the containers it comes in, I just shot some Dupont 4895 I bought over 50 years ago. Primers, I store in the ammo cans also with some desiccant bags in with them. I've never heard of the kitty litter stuff, but if it works, use it. You definitely want something in there with them. Granted, paper/cardboard boxes adsorb moisture but with a good absorbent in there with them I would think they would be ok. The biggest thing is to try and keep them in a controlled temp where there is not a lot of fluctuation, that's what causes the container to breath in and out, pulling moisture in when it cools. 2 Quote

NOC 1 Posted November 15, 2020 Posted November 15, 2020 Unlike cigars which like a 60-70% humidity ammo ideally wants a 0% humidity. The good news is that ammo is pretty tough. Think about it, you can still by ammo that has been in government storage since the 1950's and it's a cinch they aren't in climate controlled facilities. Personally I store my ammo in a 24 gun sized safe that I converted to shelving. I load my own ammo for about 15-16 calibers so it gets packaged several ways. Loose rounds go in the low flat disposable food storage containers along with a chunk of VCI foam. The stuff that ends up in boxes just goes onto a shelf in stacks. I stick a couple of larger VCI sponges in the safe and call it good. I wouldn't worry about using the VCI or desiccant packs really, but it is so cheap that why not. It really isn't that big of a thing for ammo unless you are loading some special Match ammo that uses a very light or no crimp. I'd worry more about storing your guns. Quote
Super User Angry John Posted November 25, 2020 Super User Posted November 25, 2020 Store ammunition in a cool dry place just like the components. Heat is the enemy as it speeds up the break down of the powder. Gun powder is a very complicated substance which has acids inhibitors and other fun stuff. I advocate for keeping it inside the house unless you have huge volumes. Inside a safe with a heater bar to prevent rust is probably the worst choice. Quote
