Mary and I are constantly thinking of SHTF scenarios and what to do to be prepared. Aside from food, medicinal items, clothing, etc., ammo is of course on our list. I have never stored ammo in the wild and back in February decided to try it after researching much about it on the internet. Here is one of the suggestions we went with, very simple and inexpensive. We used GI issue ammo cans in very good condition with intact seals on the lids along with 5 gallon buckets with locking lids we got at Lowes. We were liberal in our use of desiccant packs (made by running-man's neighbor at the local plant in New Mexico!). Tell him thanks running-man, they do a great job!
I have not had much faith in this method of storage in Florida where heat & humidity is the prime enemy of metallic objects. We sealed some ammo (with desiccants) in a few GI ammo cans and put them in the 5 gallon buckets with desiccants in the buckets. We then buried them on 16 February of this year. Being paranoid I began to stress about digging them up and checking them, afraid of what I might find. The wife all the time saying "leave them alone"!
I didn't listen to her, dug them up today and found.....zero evidence of any moisture. She didn't say "I told you so" just simply and graciously asked if I felt better! It has been 6 months since we buried our stash and I am impressed, I no longer fear using this method with other items in various locations.
I attribute this in large part to these packets:
