Properly storing ammunition is crucial for maintaining its reliability and safety over extended periods. Neglecting this can lead to malfunctions, decreased accuracy, and even dangerous situations. This guide provides a comprehensive overview of best practices for long-term ammo storage, covering everything from environment control to container selection.
Understanding the Enemies of Ammunition
Before diving into storage solutions, it's vital to understand what degrades ammunition over time:
- Moisture: This is the biggest enemy. Moisture causes rust and corrosion on the casing, bullet, and primer, rendering the ammunition unusable or dangerous to fire.
- Temperature Fluctuations: Extreme heat or cold can damage the propellant, leading to inconsistent performance or even spontaneous detonation in extreme cases. Consistent, moderate temperatures are ideal.
- UV Radiation: Sunlight's ultraviolet rays can degrade the propellant and casing materials, reducing their effectiveness.
- Oxygen: Oxidation can slowly degrade the components of ammunition, especially the propellant and primers.
The Key Elements of Effective Long-Term Ammo Storage
1. Environment Control: The Foundation of Success
- Temperature: Aim for a cool, dry location with a temperature between 50°F and 70°F (10°C and 21°C). Avoid attics, basements prone to flooding, and direct sunlight. A climate-controlled environment is ideal.
- Humidity: This is paramount. Ideally, maintain humidity levels below 30%. Use a dehumidifier if necessary to keep the environment dry. A hygrometer will help you monitor humidity levels accurately.
- Air Circulation: Good air circulation prevents moisture buildup and helps maintain a consistent temperature. Avoid airtight containers without proper desiccant.
2. Container Selection: Protection is Paramount
The type of container you choose significantly impacts the longevity of your ammunition. Here's a breakdown:
- Ammunition Cans: These are a popular choice, offering good protection against moisture and impacts. Look for cans with airtight seals and consider lining them with desiccant packets.
- Plastic Storage Bins: Choose high-quality, heavy-duty plastic bins with tight-fitting lids. Avoid thin, flimsy plastic that can crack or warp over time.
- Metal Cabinets/Safes: These provide superior protection against theft and environmental factors, particularly moisture and temperature fluctuations.
Important Consideration: Regardless of the container type, always use desiccant packets (silica gel) to absorb moisture. Replace them regularly, as their effectiveness diminishes over time.
3. Proper Organization and Labeling
- Caliber/Type Separation: Store different calibers and ammunition types separately to prevent accidental mixing. Clear labeling is essential.
- Lot Number Tracking: Keep track of lot numbers for each batch of ammunition. This information can be valuable if there are ever any quality control issues.
- Inventory Management: Maintain an accurate inventory of your ammunition, noting purchase dates and quantities. This helps with long-term planning and tracking.
4. Regular Inspection
Periodically inspect your ammunition for any signs of degradation, such as rust, corrosion, or propellant discoloration. If you find any issues, it’s best to dispose of the affected rounds safely according to local regulations.
Beyond the Basics: Advanced Techniques for Long-Term Storage
- Vacuum Sealing: For added protection, consider vacuum-sealing ammunition in airtight bags before placing them in their primary storage containers.
- Nitrogen Purging: For truly long-term storage, consider purging the air from your storage containers with nitrogen gas. This eliminates oxygen and greatly reduces the risk of oxidation. This is more commonly used for museum-quality preservation and is not essential for typical home storage.
Conclusion: Safeguarding Your Investment
Proper ammunition storage is not just about preserving your investment; it's about safety and reliability. By following these guidelines and paying attention to environmental factors, you can significantly extend the lifespan and usability of your ammunition. Remember, regular inspection and proactive maintenance are key to long-term success.
