Storing 9mm ammunition correctly is crucial for safety, maintaining its quality, and ensuring its longevity. Improper storage can lead to dangerous malfunctions, reduced accuracy, and even spontaneous combustion. This comprehensive guide will walk you through the best practices for storing your 9mm ammo, covering everything from the ideal environment to the best containers.
Understanding the Enemies of 9mm Ammo
Before diving into storage solutions, let's identify the primary factors that can degrade your ammunition:
-
Moisture: Humidity is the biggest threat to ammunition. It can cause corrosion on the casing, leading to malfunctions and potentially dangerous situations. Rust can also affect the bullet itself, impacting accuracy and reliability.
-
Temperature Extremes: Extreme heat can cause the propellant to degrade, potentially leading to dangerous pressure increases within the cartridge. Freezing temperatures, while less damaging, can still negatively impact the integrity of the ammunition.
-
Sunlight (UV Rays): Prolonged exposure to ultraviolet light can degrade the propellant and the casing, reducing the lifespan and reliability of your ammunition.
-
Improper Handling: Rough handling or dropping ammunition can damage the primers or bullets, increasing the risk of malfunctions.
Optimal Storage Environment for 9mm Ammo
The ideal storage environment for your 9mm ammunition minimizes the negative factors listed above:
-
Cool and Dry: Aim for a temperature between 50°F and 70°F (10°C and 21°C) and a relative humidity below 50%. A climate-controlled space is ideal. Avoid basements prone to flooding or attics where temperatures fluctuate wildly.
-
Dark: Store your ammo away from direct sunlight or other sources of ultraviolet light. A dark closet or cabinet is a good choice.
-
Stable: Choose a location free from vibrations or shocks. Avoid areas where the ammo could be bumped or dropped.
Choosing the Right Storage Containers
The container you choose significantly impacts the longevity and safety of your 9mm ammo:
Ammunition Cans:
- Pros: Metal ammunition cans offer excellent protection against moisture and crushing. They are often sealed tightly. Many come with desiccant packs to help absorb moisture.
- Cons: Metal cans can rust if not properly sealed and maintained. They can also be heavy and bulky.
Plastic Ammo Boxes:
- Pros: Lightweight, stackable, and relatively inexpensive. They offer decent protection from dust and minor impacts.
- Cons: Generally provide less protection against moisture than metal cans. The quality varies considerably, so choose sturdy boxes from reputable brands.
Waterproof Cases:
- Pros: Offer superior protection from moisture, making them ideal for storing ammunition in humid environments or outdoor storage.
- Cons: Can be more expensive than other options. Ensure they are properly sealed to prevent moisture intrusion.
Vacuum-Sealed Bags:
- Pros: Excellent protection against moisture and oxygen. Can extend the life of ammunition significantly.
- Cons: Requires a vacuum sealer, making this option less convenient than others.
Important Note: Regardless of the container you choose, always use a desiccant pack inside to absorb any remaining moisture. These are inexpensive and readily available at sporting goods stores.
Additional Tips for Safe 9mm Ammo Storage:
- Separate by Lot Number: If possible, separate your ammunition by lot number. This helps track potential manufacturing defects or quality issues.
- Label Clearly: Clearly label your containers with the caliber (.9mm), quantity, and date of purchase.
- Regular Inspection: Periodically inspect your ammunition for any signs of corrosion, damage, or deterioration.
- Secure Storage: Always store your ammunition securely, away from children and unauthorized individuals. Consider using a gun safe or locking cabinet.
By following these guidelines, you can ensure your 9mm ammunition remains safe, reliable, and ready for use for years to come. Remember, proper storage is not just about preserving your investment; it's about responsible gun ownership and safety.
