How to Store Ammo Long-Term

Keep ammunition reliable for years with the right conditions and containers.

1. 1
   Control humidity

   Moisture is the enemy. Store ammo in a cool, dry place and toss desiccant packs in your containers to absorb humidity.

2. 2
   Use sealed containers

   Military-style ammo cans with a good rubber gasket are ideal — airtight, stackable, and rugged. Label by caliber and date.

3. 3
   Keep it cool and stable

   Avoid attics and garages with big temperature swings. A closet interior wall or basement (if dry) is better.

4. 4
   Rotate your stock

   Shoot your oldest ammo first and replace it. Modern, properly stored ammo lasts decades, but rotation keeps everything fresh.
