Long-Term Ammunition Storage: 6 Recommendations for Success

December 28, 2023

Ensuring the longevity and reliability of your ammunition is paramount for any firearm owner. Long-term storage of ammunition requires careful consideration and proper techniques to prevent degradation and maintain peak performance. It’s crucial to equip yourself with the knowledge and tools necessary to safeguard your ammunition investment. This article explores the best practices for storing ammunition over the long haul.

1. Choose the Right Containers:

The first step in preserving ammunition is selecting the right storage containers. Select airtight, moisture-resistant containers such as military surplus ammo cans or commercially available plastic or metal containers with rubber gaskets. These containers help create a barrier against external elements that can compromise the integrity of the ammunition.

2. Control Temperature and Humidity:

Temperature and humidity control are key factors in preventing ammunition from deteriorating. Store your ammo in a cool, dry environment to mitigate the risk of corrosion and moisture absorption. Ideally, aim for a temperature range between 50°F and 70°F and a humidity level below 60%.

3. Desiccants and Moisture Absorbers:

To further combat humidity, include desiccant packets or moisture-absorbing products within the storage containers. Silica gel packs are commonly used and can effectively absorb excess moisture, helping to prevent rust and corrosion on casings and bullets.

4. Vacuum Sealing:

Consider vacuum-sealing your ammunition for an added layer of protection. Vacuum-sealed bags remove air and create a sealed environment, minimizing the risk of oxidation and slowing down the aging process of the ammunition components.

5. Store in Original Packaging:

Whenever possible, store ammunition in its original factory-sealed packaging. This packaging is designed to protect the ammunition from environmental factors and provides an extra layer of insulation. If the original packaging is damaged, consider resealing it using a vacuum sealer.

6. Rotation and Inspection:

Regularly rotate your supply to ensure that older ammunition is used first, following the "first in, first out" principle. Additionally, inspect your stored ammunition periodically for signs of corrosion, discoloration, or damage. Correctly discard any cartridges that show signs of compromise to maintain the overall quality of your ammunition supply.

By investing in proper storage containers, controlling environmental conditions, and employing techniques such as vacuum sealing and desiccant use, you can ensure that your ammunition remains in peak condition for years to come. Taking these precautions will not only preserve the integrity of your investment but also provide peace of mind knowing that your ammunition is ready when you need it most.
