I know that the best way to store ammo is in a cool, dry atmosphere. All of my ammo is stored in those steel GI cans with a desiccant thrown in. At this point all of is located in the basement (very cool and dry). I really don't want to keep all my 'eggs in one basket' so to say. With this in mind, I'd like to move some of it to my attic (unheated& uncooled). Unfortunately my attic gets hot during the summer. The maximum temp recorded up there was 90 degrees. There's a mushroom fan up there that is thermostatically controlled. I was wondering if there would be any problems keeping some of my stock up there. Here in the northeast basically there's four months worth of those hot temps. Thanks.
