Proper ammunition storage is crucial for maintaining its reliability and safety over the long term. Improper storage can lead to corrosion, degradation of the propellant, and even dangerous malfunctions. This guide provides comprehensive advice for long-term ammunition storage, encompassing best practices for various ammunition types and environmental considerations.
Understanding the Enemies of Ammunition
Before diving into storage solutions, it's vital to understand what damages ammunition:
- Moisture: This is the biggest enemy. Moisture leads to rust and corrosion on the casing and projectile, and it can also degrade the gunpowder, making it unreliable or potentially dangerous.
- Temperature Fluctuations: Extreme heat or cold can damage the propellant and casing. Consistent, moderate temperatures are ideal.
- UV Radiation: Sunlight's ultraviolet rays can break down the components of ammunition, accelerating degradation.
- Oxygen: While not as immediate a threat as moisture, prolonged exposure to oxygen can contribute to the slow oxidation of components.
Best Practices for Long-Term Ammunition Storage
Here's a breakdown of the optimal strategies for preserving your ammunition:
1. Selecting the Right Container
- Ammunition Cans: Steel ammunition cans with airtight seals are a popular and effective choice. Ensure the seals are intact and consider adding desiccant packs (explained below) for extra protection.
- Plastic Storage Containers: High-quality, airtight plastic containers are a viable alternative, but be sure they are made of a material resistant to chemicals and won't degrade over time. Avoid using recycled plastic containers.
- Vacuum-Sealed Bags: These bags remove air, minimizing oxidation, but are generally less effective against moisture unless combined with desiccant packs.
2. The Importance of Desiccants
Desiccant packs (often silica gel) absorb moisture from the air. These are essential for long-term storage, especially in humid environments. You can purchase desiccant packs readily online or at sporting goods stores. Remember to replace them periodically, as they become saturated with moisture.
3. Environmental Considerations
- Temperature: Aim for a cool, dry, and stable temperature between 50°F and 70°F (10°C and 21°C). Avoid attics, basements prone to flooding, or areas exposed to direct sunlight.
- Humidity: Low humidity is crucial. A dehumidifier might be necessary in damp climates.
- Location: Store ammunition in a secure, dark, and inaccessible location away from children and unauthorized individuals.
4. Organization and Inventory
- Labeling: Clearly label each container with the ammunition type, caliber, quantity, and date of storage. This helps maintain an accurate inventory.
- Inventory Management: Keep a detailed inventory record, noting the storage location and any relevant information. Regularly check your inventory for any signs of damage or degradation.
Specific Ammunition Types and Considerations
While the general principles apply to all ammunition types, some require special attention:
- Rimfire Ammunition: Rimfire rounds (e.g., .22LR) are notoriously sensitive to moisture and should be stored with extra care and desiccant.
- Black Powder Ammunition: Black powder is highly susceptible to moisture and should be stored in an extremely dry environment.
Regular Inspection is Key
Periodically inspect your stored ammunition for any signs of corrosion, damage, or degradation. If you notice any problems, it's best to consult with a firearms expert or ammunition manufacturer.
