I have more ammo than I have room for on my current ammo rack and within my safe. I'm looking for a cheap (<$150) solution to store around 20,000+ rnds in the factory ammo boxes they came in(not interested in dumping them loosely into ammo cans at this time). I would like to be able to seal the storage unit up a bit so I can control humidity via a dry rod and some reusable desiccant packs. I am looking for something like a metal locker/cabinet with shelving that can hold around 80-100+lbs per shelf. I can devise a way to make it seal up decently...
I have metal NSF racks from Menards...The shelves can't hold what I need them to. I also have a humidity controlled room but have gotten tired of having to empty the dehumidifier(no near by drain to run it to) and the "wasted" electricity from it constantly running. If I had the option to run my dehumidifier to a drain, I would consider just building some wooden shelves(wouldn't reduce the electricity usage though).
Suggestions?
