Proper ammunition storage is essential for preserving its reliability and ensuring safety. Whether you’re a seasoned gun owner or just starting to build your ammo stash, knowing the best practices for storage can save you money, time, and frustration. Improper storage can lead to moisture damage, corrosion, or even degraded performance over time. Here’s a guide to help you store your ammunition safely and effectively.
Keep It Cool and Dry

The golden rule for storing ammo is to keep it in a cool, dry place. Fluctuations in temperature and high humidity are the biggest threats to ammunition. Heat accelerates the breakdown of powder and primer compounds, while moisture can corrode metal casings. Basements and attics, which often experience temperature spikes or damp conditions, are poor choices for storage. Instead, aim for a climate-controlled area, like a closet in your living space.
Avoid the Floor

Storing ammunition directly on the floor, particularly in basements or garages, exposes it to potential water damage from leaks or flooding. Elevate your storage containers to keep them safe from unexpected water exposure. Simple shelves or pallets can add an extra layer of protection, ensuring your ammo stays dry and secure.
Use Airtight Containers

While factory boxes are convenient for identifying caliber and specifications, they don’t offer sufficient protection against environmental factors. Airtight containers, such as military-grade ammo cans or even sturdy plastic bins, are ideal for long-term storage. For added security, toss in some silica gel packs to absorb any residual moisture and maintain optimal dryness within the container.
Label Everything Clearly

If you’re using alternative storage solutions, like plastic containers or custom ammo boxes, always label them clearly. Include details such as caliber, bullet weight, and load information. This is especially crucial for reloaders who make their own ammunition. Accurate labeling prevents confusion and ensures you know exactly what you’re handling when it’s time to use the ammo.
Keep Ammo Separate from Firearms

Safety is paramount when storing ammunition. Always store it separately from firearms to reduce the risk of unauthorized access. This separation is particularly important in homes with children or guests who may not be familiar with firearm safety protocols. Locking storage cabinets or safes provide an additional layer of security, keeping your ammunition out of the wrong hands.
Don’t Open and Close Containers Frequently

Once you’ve sealed your ammo in an airtight container, resist the temptation to open it repeatedly. Each time you open the container, you introduce moisture and air, which can compromise the integrity of the ammo over time. Aim for a “set it and forget it” approach—store your ammo securely and only access it when necessary.
Understand Long-Term Storage Safety

One common misconception about ammunition is that it poses a fire or explosion risk during storage. In reality, small-caliber ammunition is relatively stable and unlikely to cause significant hazards, even in a house fire. Proper storage is more about preserving functionality and reliability than avoiding danger. With good practices, your ammunition can last for decades without issues.
Avoid Temperature Cycling

Temperature cycling, where ammo experiences frequent changes in temperature, can degrade its components. For instance, leaving ammunition in a hot car or near a heating vent can significantly reduce its shelf life. Consistency is key – keep your ammo at a steady room temperature to ensure optimal performance.
Protect Against Corrosion

Even a small amount of moisture can lead to rust or corrosion on brass or steel casings. This not only affects the appearance of your ammunition but can also cause feeding or extraction issues in firearms. Regularly inspect your stash for any signs of damage, especially if you’re storing older ammunition. Discard any rounds with significant corrosion to avoid potential malfunctions.
Don’t Store Ammo in Extreme Locations

While it might seem convenient, garages, sheds, or other outdoor storage spaces are unsuitable for ammunition. These areas are often exposed to wide temperature swings and high humidity, making them prime locations for damage. Stick to indoor, controlled environments to ensure your ammo stays in peak condition.
Silica Gel Packs: A Simple Solution

Silica gel packs, often included in packaging for electronics or shoes, are inexpensive and highly effective tools for maintaining a dry storage environment. Place a few in your ammo containers to absorb any moisture that might sneak in. For best results, replace the packs periodically or use reusable ones that can be dried out and reused.
Why Good Storage Matters

Ammo is an investment, both in terms of cost and safety. Proper storage ensures that every round functions as intended when you need it. I find it fascinating how such simple precautions – like using silica gel or avoiding heat exposure – can make a huge difference in performance. It’s a reminder of how small details in preparation can have significant impacts in the field.
Smart Storage, Reliable Ammo

Storing ammunition properly isn’t just about keeping it dry – it’s about maintaining its reliability, extending its lifespan, and ensuring safety. By following these simple do’s and don’ts, you can protect your investment and have peace of mind knowing your ammo will be ready when you need it. With a little care and attention, your stockpile will stay in perfect condition for years to come.
