Tips for Extending the Shelf Life of Ammunition

Extending the shelf life of your ammunition is essential to firearm safety and effectiveness. Proper storage and maintenance can help ensure your ammunition is reliable for as long as possible. Here are the top ways to extend the shelf life of your ammunition:

• Store in a cool, dry place: Ammunition should be stored in a location where temperature and humidity levels are stable. Avoid extreme heat, cold, and damp environments, as moisture can lead to corrosion and reduce the effectiveness of powder and primers.
• Use airtight containers: Use airtight metal or plastic containers, ammo cans, or vacuum-sealed bags to protect your ammunition from moisture and contaminants. These containers can also prevent exposure to oxygen, which can lead to oxidation.
• Keep it away from direct sunlight: Ultraviolet (UV) rays from sunlight can degrade the quality of ammunition over time. Store your ammunition in a dark or shaded area to prevent UV exposure.
• Use desiccants: Place desiccant packs or silica gel inside your storage containers to help absorb moisture and maintain low humidity levels.
• Inspect regularly: Check your ammunition for signs of damage or corrosion on a regular basis. Look for dents, rust, or discoloration. If you find damaged rounds, dispose of them properly.
• Rotate stock: If you have a substantial ammunition collection, practice a “first in, first out” (FIFO) approach. Use older ammunition before newer purchases to ensure nothing sits in storage for too long.
• Label and date: Clearly label your ammunition containers with the date of purchase or storage to help you keep track of when they were sealed. This allows you to monitor the age of your ammunition and replace it as necessary.
• Avoid exposure to solvents and oils: Keep ammunition away from solvents, oils, and chemicals that can damage the casing, primer, or powder. Store ammunition separately from cleaning supplies and firearms.
• Handle with care: Avoid dropping or rough handling, as it can damage the primer and reduce reliability.
• Use corrosion inhibitors: Use corrosion-inhibiting products specifically designed for ammunition storage. These products create a protective barrier against moisture and oxidation.
• Maintain proper firearm storage: Properly storing your firearms also indirectly affects ammunition. A securely stored firearm is less likely to be exposed to environmental conditions that could harm your ammunition.
• Follow manufacturer recommendations: Different ammunition manufacturers may have specific guidelines for storage. Check the packaging or manufacturer’s website for any recommendations related to storage and shelf life.

Remember that even with proper storage, ammunition does have a finite shelf life. Over time, the chemical composition of the powder and primers can change, affecting performance. It’s a good practice to periodically replace older ammunition with fresh stock to maintain reliability and safety.
