I store ammo in USGI ammo cans. I use silica gel packets to help absorb moisture. Every 6 months or so, I heat the gel packs in an oven set to 225 for about 30 minutes to get rid of any absorbed moisture.

Never store loose, bulk powder or primers in a USGI ammo can. Once you latch the can, you have a bomb.

Never store loose powder or primers in a gun safe for the same reason.

I keep my dies in die boxes on a shelf, powder and primers are kept in original packages, on an open shelf.

1: Plastic ammo cans similar to the metal USGI cans, MTM brand I think.

2: Powder and primers are just stored in their original containers in a wooden cabinet - in an air conditioned room. Ditto with dies and all other reloading supplies. I used to keep them in the shop, but I had problems with rust.

3: I have metal desiccant packs that can be refreshed in the oven. There is a little window and when it turns pink it's time to refresh it.

All my ammo goes in MTM cases and in a cupboard up high. No issues with moisture really here in SD but I do keep the gun room temp and humidity controlled. Same with reloading supplies. In original containers in a cool dark dry cupboard. Never had an issue yet thank goodness. If it’s not reloaded ammo it stays in the factory box but I don’t have much new ammo around. That is pretty rare these days.
