Storing Ammo Long-Term
Temperature, humidity, containers, and shelf life — how to store ammunition so it stays reliable years later.
The Quick Take
Modern ammunition, stored properly, stays reliable for decades — the enemies are moisture and big temperature swings, not age. Keep it cool, dry, and stable: a sealed ammo can with a desiccant pack in a closet or dry basement beats an attic or a humid garage. Label cans by caliber and date so you can rotate.
Avoid common mistakes like storing loose ammo in damp areas or stacking it near heat sources, and rotate your stock by shooting the oldest first. There's no need for exotic measures — airtight containers and a stable environment are 90% of the battle. The questions below cover containers, humidity control, and real-world shelf life.
