Ok. Then I would recommend getting the military issue metal can and throw some dessicant into it. Since ammo is so heavy, you might want to get the .50 caliber or .30 if you plan on moving it around or if you want different calibers to have their own box. You can buy dessicant in bulk from craft stores like Hobby Lobby, Michaels, etc. and reuse it (just bake it in the oven to restore its dessicant value if you wish). Put it into plastic or a suitable mesh container with holes to allow circulation or cloth containers with zippers etc. If you are really cheap, you can save all of those dessicant packages that come with all sorts of goods you buy, take them out of the packages, reheat in the oven, and reuse over and over again. At 7.99 each, that Natchez has, that is a smoking deal. Unfortunately, I am in the area where Natchez won't ship due to competition with its retail dealers but I think you are okay and gtg with them.
