For any prepper, stocking up on ammunition is essential for survival, whether for self-defense, hunting, or bartering in a crisis. Ammo doesn’t expire quickly, but storing it improperly can ruin its effectiveness when you need it most. You must follow some important steps to ensure your stockpile remains in prime condition for years – if not decades. Let’s dive into seven must-know tips for long-term ammo storage and additional insights on why proper storage matters.
1. Keep It Dry to Prevent Corrosion

Moisture is the enemy of ammo. Over time, even a little humidity can cause metal casings to rust and primers to degrade, making your ammunition unreliable or even dangerous. The key to keeping your ammo dry is controlling the humidity around it. Store your ammo in an airtight container with a moisture absorber, like silica gel packets. If you live in a particularly humid area, consider a dehumidifier in your storage space to protect your ammo from the elements.
2. Cool Temperatures Help Preserve Longevity

Storing your ammunition in a cool environment is just as important as keeping it dry. Heat can cause the gunpowder in your ammo to break down, reducing its performance and even making it unsafe to use. Ideal ammo storage occurs in rooms with a stable, cool temperature – preferably air-conditioned. If you must store it in a less stable environment, like a garage or shed, ensure the containers are well-sealed and insulated from temperature swings.
3. Keep Ammo in the Dark

Sunlight can damage more than just your skin – it can also harm your ammunition. UV rays can degrade the materials that make up the casings and boxes, leading to quicker wear and tear. If sunlight can penetrate your storage area, it can also heat up your ammo, contributing to the temperature problems mentioned earlier. The best practice is to keep your ammo in a dark, cool place away from prying eyes, like a basement or closet.
4. Choose the Right Container for the Job

A high-quality container is a game-changer when it comes to ammo storage. Military-grade ammo cans are your best bet, designed specifically to protect ammunition from moisture, dust, and temperature fluctuations. These metal or plastic containers come with durable seals that keep out the elements. When purchasing, inspect the seal to ensure it’s intact, as any small tear or crack will compromise its ability to keep your ammo safe.
5. Organize Your Stockpile for Easy Access

Proper organization is critical for keeping your ammo in good condition and making it easily accessible when you need it. Label your containers by caliber and type, so you don’t need to open multiple cans just to find what you’re looking for. Keeping track of what’s inside will also help you maintain the integrity of your long-term storage. Have a separate, easily accessible container for commonly used ammo that doesn’t interfere with your long-term stash.
6. Store Popular Calibers for Future Barter

Even if you own guns of different calibers, it’s wise to stockpile the most popular ones for future trade value. In a SHTF scenario, certain calibers will be in high demand, not just for use but also for barter. The .22 LR, .223, .308, and 9mm are just a few examples of rounds that many gun owners will be searching for. Even if you don’t own guns that use these calibers, having some on hand could provide you with leverage in a tough situation.
7. Don’t Overlook the Importance of Desiccants

One often overlooked but essential component of ammo storage is the desiccant. These moisture-absorbing packets help remove any trapped humidity inside your container, keeping your ammunition dry and functional. Silica gel packets are a common and affordable option, but they need to be checked and reactivated (by baking them in the oven) from time to time. Some higher-end desiccants may last longer and require less maintenance, offering peace of mind for your long-term ammo storage needs.
Protecting Your Ammo Investment

Ammunition isn’t cheap, especially during times of high demand or scarcity. Storing your ammo improperly could cost you a significant investment and leave you unprepared during a crisis. When done correctly, long-term storage ensures your stockpile is ready to serve you when it’s most needed, without any issues related to corrosion, misfires, or degradation. Think of your ammo as a future currency and treat it with the same care you would your financial assets.
Long-Term Storage Strategies for Preppers

For preppers, ammunition isn’t just a tool – it’s an investment in your survival strategy. Besides its practical uses, ammo will likely become a valuable commodity in a post-collapse world. The key to maximizing its value lies in your ability to store it safely for long periods. With proper organization and the right conditions, your ammunition will be as reliable ten years from now as it is today.
What Happens if You Don’t Store Ammo Properly?

Failing to follow these storage guidelines could render your ammo useless when you need it the most. Rusted casings, degraded primers, and corroded bullets will lead to jams, misfires, or worse. Not to mention, damaged ammo can be dangerous, potentially harming your weapon or even you. Take the time now to ensure you’re doing everything you can to avoid future headaches or dangerous situations.
Ammo Storage: Not Just for Preppers

While preppers have a particular interest in long-term storage, anyone who owns a firearm should pay attention to how they store their ammo. Even occasional shooters can benefit from keeping their ammo in optimal condition. After all, what’s the point of having a stockpile if it isn’t functional when you need it?
Make Sure Your Ammo is Ready When You Need It

The seven tips outlined here will help you ensure that your ammunition remains in top condition for years, if not decades, to come. Storing ammo correctly is essential for self-defense, hunting, or even trading in a survival situation. Take the time to organize, protect, and maintain your stockpile – your future self will thank you.
Impact of Changing Climate Conditions

What are your thoughts? How do you think changing climate conditions in different parts of the world could impact the long-term storage of ammunition? In a post-collapse world, do you believe ammunition will hold more value for bartering or for personal use, and why?
