If you're storing ammunition, don't forget about humidity. Pack that ammo away in a sealed can in the summer on a low humidity day. Wear gloves to keep the fingerprints off. Also, put in some of those dessicant paks. If you're using stripper clips, cardboard sleeves & cloth bandoliers, dry them out in the oven or clothes drier first. Otherwise, you may open the can to find your precious brass covered with green corrosion. I speak from experience.
