Storing ammunition for the long term requires careful consideration to maintain its reliability and safety. Improper storage can lead to corrosion, degradation of the propellant, and even dangerous malfunctions. This comprehensive guide outlines the best practices for long-term ammo storage, ensuring your rounds remain dependable for years to come.
Understanding the Enemies of Ammunition
Before diving into storage solutions, let's identify the primary factors that degrade ammunition over time:
-
Moisture: This is the biggest enemy. Moisture leads to rust and corrosion on the casing and projectile, potentially causing malfunctions or rendering the ammunition unusable. It can also damage the propellant, reducing its effectiveness or causing it to become unstable.
-
Temperature Fluctuations: Extreme heat or cold can negatively impact the propellant, causing it to degrade faster. Consistent temperatures are ideal.
-
UV Radiation: Exposure to sunlight's ultraviolet radiation can also degrade the propellant and casing materials.
-
Air: Oxygen in the air contributes to oxidation and corrosion. Reducing exposure to air is crucial.
-
Contaminants: Dust, dirt, and other airborne particles can compromise the integrity of the ammunition.
Optimal Storage Conditions for Long-Term Ammo Preservation
The ideal environment for long-term ammo storage mimics a cool, dry, and dark vault:
-
Temperature: A cool, stable temperature between 50°F and 70°F (10°C and 21°C) is recommended. Avoid extreme temperature fluctuations.
-
Humidity: Low humidity is essential. Aim for a relative humidity (RH) below 50%. A dehumidifier might be necessary in humid climates.
-
Darkness: Store ammunition away from direct sunlight and UV radiation. A dark, opaque container is ideal.
-
Cleanliness: Keep the storage area clean and free from dust, dirt, and other contaminants.
Choosing the Right Storage Containers
The container you choose plays a vital role in protecting your ammunition. Here are some excellent options:
1. Ammo Cans:
- Pros: Durable, stackable, often airtight or watertight, readily available, relatively inexpensive.
- Cons: May not be completely airtight unless specifically designed for long-term storage.
2. Plastic Storage Bins:
- Pros: Lightweight, stackable, relatively inexpensive.
- Cons: Not as durable as metal cans, may not be airtight, can degrade over time.
3. Vacuum-Sealed Bags:
- Pros: Excellent for removing air and moisture, can be used in conjunction with other storage methods.
- Cons: Requires a vacuum sealer, may not be ideal for long-term storage on their own.
4. Climate-Controlled Safes:
- Pros: Provides the most consistent temperature and humidity control, ideal for valuable or large collections.
- Cons: Most expensive option, requires a significant investment.
Preparing Ammunition Before Storage
Before storing your ammunition, take these steps to enhance its longevity:
-
Inspect for Damage: Check each round for any signs of damage, such as dents, rust, or corrosion. Discard any damaged rounds.
-
Clean Ammunition (If Necessary): If you've handled the ammo in less-than-ideal conditions, consider lightly cleaning it with a dry cloth. However, excessive handling can damage the primer, so use caution.
-
Organize and Label: Clearly label each container with the type of ammunition, caliber, quantity, and date of storage.
Long-Term Storage: Best Practices
-
Rotate Your Stock: While proper storage significantly extends the lifespan of ammunition, it's a good practice to rotate your stock periodically. Older ammunition should be used before newer ammunition.
-
Regular Inspection: Periodically check your ammunition for any signs of degradation or damage.
-
Avoid Extreme Conditions: Never store ammunition in areas exposed to extreme temperatures, humidity, or direct sunlight.
Conclusion
Proper long-term ammunition storage is crucial for maintaining its reliability and safety. By following these guidelines, you can help ensure that your ammunition remains dependable for years to come. Remember, safety should always be your top priority when handling and storing ammunition. Always consult local regulations and laws regarding ammunition storage in your area.
