I've been storing all of my completed ammo in 100 pack boxes in various colors as I can get them for different bullet weights or different guns of the same caliber. I've got several hundred of most of my calibers loaded up and am getting tired of buying boxes. I like the boxes for going to the range and they stack nice. Anybody have any solutions for storing extra rounds? I don't know that tupperware would be much cheaper and ziplock baggies make me worry about humidity.
