Storing ammunition long-term requires more than just tossing boxes in a closet. Proper storage is crucial to maintaining the integrity and safety of your rounds, preventing degradation and ensuring they're reliable when you need them. This comprehensive guide delves into the best practices for long-term ammo storage, covering everything from environmental factors to container selection.
Understanding the Enemies of Ammunition
Before diving into storage solutions, it's vital to understand what can damage your ammunition over time. These primary culprits dictate the strategies you'll employ:
- Moisture: This is arguably the biggest threat. Humidity causes rust on metallic casings and can lead to corrosion within the cartridge itself, rendering rounds unreliable or even dangerous to fire.
- Temperature Fluctuations: Extreme heat and cold can cause propellant degradation and damage to primers, affecting the ammunition's performance and potentially leading to misfires or malfunctions.
- UV Radiation: Prolonged exposure to ultraviolet (UV) light can degrade the powder and weaken the casing, reducing the lifespan and reliability of your rounds.
- Oxygen: Exposure to air, and specifically oxygen, can accelerate the degradation process of the gunpowder.
- Contaminants: Dust, dirt, and other debris can compromise the integrity of the ammunition and lead to malfunctions.
Best Practices for Long-Term Ammunition Storage
Employing these best practices will significantly extend the life and reliability of your ammunition:
1. Selecting the Right Storage Container
The container you choose is paramount. Avoid using cardboard boxes, as they're susceptible to moisture and pests. Consider these options:
- Metal Ammunition Cans: These offer excellent protection against moisture, light, and contaminants. Look for cans with tight-fitting lids and consider using desiccant packs (more on those below) for extra protection.
- Plastic Storage Bins: High-quality, airtight plastic bins can be a good alternative, especially if you're storing a large quantity of ammunition. Ensure they're UV-resistant and free of any chemicals that could react with the ammunition.
- Vacuum-Sealed Bags: These are excellent for removing oxygen and protecting smaller quantities of ammunition. However, they're not suitable for long-term storage without periodic checks and potential re-sealing.
2. Controlling the Environment
The storage environment plays a crucial role in preserving your ammunition. Aim for:
- Cool and Dry Location: A temperature between 50°F and 70°F (10°C and 21°C) and relative humidity below 50% is ideal. Avoid attics, basements prone to flooding, and garages subject to extreme temperature swings.
- Dark Environment: Minimize exposure to direct sunlight and UV light. A dark closet or storage room is preferable.
3. Using Desiccants
Desiccants, like silica gel packets, absorb moisture from the air. These are highly recommended for long-term ammunition storage, especially in humid environments. You can purchase them in bulk or reuse those found in packaged goods (ensure they are still active).
4. Regular Inspection
Periodically inspect your ammunition for any signs of damage, rust, or corrosion. This allows you to address any issues promptly and prevent further degradation.
5. Proper Handling
Always handle ammunition carefully to avoid damage. Avoid dropping or jostling containers, and never store ammunition near sources of heat or open flames.
6. Labeling and Organization
Clearly label each container with the type of ammunition, caliber, and date of storage. This helps with inventory management and ensures you can quickly locate what you need.
Advanced Techniques for Long-Term Ammo Storage
For those seeking the ultimate in long-term preservation:
- Nitrogen Purging: Filling containers with nitrogen gas displaces oxygen, slowing down the degradation process considerably. This is a more advanced technique typically employed by serious collectors or those storing very valuable ammunition.
- Rotary Canister Storage: These specialized containers rotate slowly, promoting even temperature distribution and further reducing the chances of moisture build-up.
Conclusion
Proper long-term ammunition storage is a vital aspect of responsible firearm ownership. By following these techniques, you can ensure your ammunition remains safe, reliable, and ready for use for years to come. Remember, prevention is key, and a little extra effort in storage can save you significant headaches and potential dangers down the line. Regular checks and maintenance are critical components of any successful long-term ammo storage plan.
