Proper ammunition storage is crucial for maintaining reliability and safety. Avoid storing ammo in cardboard boxes in damp environments, as this leads to moisture absorption and corrosion. Utilize airtight containers like ammo cans and control humidity with desiccants like silica gel packs. Heat accelerates gunpowder and primer degradation, so store ammo at stable room temperatures. Reloading primers are particularly vulnerable to moisture and require strict airtight storage.
