How Long Does Ammo Last in Storage?

How long does ammo last in storage?

Factory-made centerfire and rimfire ammunition kept cool, dry and sealed can stay reliable for decades. The enemies are moisture, heat swings and rough handling, not age on its own. Store it in a sealed ammo can with a desiccant pack, keep it off a bare concrete floor, and avoid attics, car trunks and damp basements. Before you shoot older rounds, look for green corrosion on the brass, dented cases, or loose bullets, and set aside anything that looks wrong. Rotate your stock by using the oldest boxes first, keep the original packaging so you can read the lot numbers, and give your storage spot a quick check every few months. Steady room temperature matters more than any single trick.
