Ammo can with a rubber seal, couple packs of silica gel, and a high & dry location with fairly consistent temperatures will keep ammo happy.
I've got several hundred rounds of mil surp .30-06 M2 Ball ammo (and more on the way) that I'll be storing in .30-cal ammo cans. My plan was to toss one of those silica gel packs in there to keep things dry. Any recommendations on what works well? Ideally I'd like someting that I can "recharge" in the oven if necessary. I was thinking something like this: http://www.amazon.com/gp/product/B00...=AZH3ZGBZ7A7O1
Dont know how much space is in an ammo can but if you get some tight mesh like a speaker grill, you could get some rice and put it in the bottom of the can. Then just lay the speaker grill on top and put the ammo on top of that. Recharge is as simple as emptying the rice and refilling. If you are a bit more skilled you could secure the grill in place and then make the bottom removable. When you need to change the rice out you just open the bottom and refill without needing to remove the ammo.
