Why It Is Important to Store Ammo Correctly

First of all, storing ammo the right way is just as important as storing your guns properly – after all, a gun isn’t much use without ammo. But while it might seem easy – just keep your bullets somewhere safe – there’s more to it than that.

Keeping Ammo Dry and Cool

How long your ammo lasts depends on the conditions in which it’s stored. This is where we should talk about humidity and temperature fluctuations.

High humidity is the worst, as it can ruin your stock ammo just like that. If you keep your ammo in a place with high moisture levels, the brass casings can corrode. Even a little rust can make your ammo less accurate. So remember that the best humidity level for storing ammo is usually between 30-50%.

Temperature changes can also affect your ammo shelf life. Extreme heat and freezing temperatures can change the nitrocellulose (a highly flammable smokeless compound used in modern ammunition) in your gunpowder.

When it gets too hot, ammo can “sweat,” and the nitrocellulose inside turns into gas. Once it gets above around 125°F, the gas starts to leak out of the cartridge. This can create uneven pressure in your gun chamber. On the other hand, very cold temperatures might not be as bad, but they can interfere with ballistic bullet performance. To avoid these problems, it’s best to keep your ammo at room temperature.

Preventing Misuse

The best way to keep your ammo safe is to keep it inaccessible to anyone but you. This means keeping it away from children and other family members in your house unless you say it’s okay. The most effective way to do this is to store ammo separately from your firearms and in a lockable box or safe.

Keeping Ammo Organized

It’s really important to keep your ammo organized and arranged neatly. Imagine you’re in a hurry and need to find a specific type of bullet. If your ammo is all jumbled up, it can be hard to find what you need quickly. But if it’s organized, you can easily reach for the right box or can and grab what you need. Plus, when your ammo is neatly arranged, it’s easier to see if you’re running low on anything, so you’ll know when to restock.

Ammo Storage: Cans, Boxes, and Safes

Let’s talk about different ways to keep your ammo safe. The three main methods are using cans, boxes, or safes. If you’re looking for non-lockable options, ammo cans and boxes are great choices. Unlike the original packaging often made of flimsy cardboard, which doesn’t offer much resistance to moisture or physical impact, ammo cans and boxes are made from durable materials, like plastic, metal, or wood. Ideally, these cans and boxes can be stored in an ammo safe, creating an ideal storage environment. Let’s unpack these options further.

Ammo Cans vs. Ammo Boxes

Ammo cans and boxes are both good for storing ammo but have different features. Essentially, ammo cans are often designed to store ammunition loosely, without any compartments. In contrast, ammo boxes feature individual compartments for each round.

Why Use Ammo Boxes?

ammo-box

Ammo boxes have separate sections for each round. This can be helpful for several reasons:

  • When each round has its own spot, it’s easy to see how much ammo you have left.
  • When going to a shooting range, it’s easy to take just the right amount of ammo with you.
  • You can avoid mixing up different calibers and loads by keeping them in separate compartments. In particular, it helps prevent mix-ups of regular and +P ammo.
  • The bullets won’t move around as much when they each have their own spot.

Why Use Ammo Cans?

ammo-can

Ammo cans are strong containers that can hold a lot of rounds. Designed originally for military use, they’re especially good for storing bulk ammo that you want to keep safe from wetness or dampness. To further enhance protection against corrosion, you can add desiccant packs. While there’s a slim chance of rounds getting jostled to the point where a bullet could become unseated or a crimp might fail, this isn’t a big concern in most cases.

Here are some reasons to use ammo cans:

  • If you have a lot of ammo in one caliber and load, you can put it all together in a can to save space.
  • If you close the can properly, it can stop water from getting inside and damaging your ammo, offering protection against floods or pipe bursts.

Ammo Lockers

If you want to be really secure, you should store your ammo in a gun safe. Many safes have special compartments where you can put your ammo. Even without these compartments, most safes feature at least one shelf suitable for storing bulk ammo.

Where ammo lockers shine compared to cans and boxes, besides lockability, is fire resistance. Fire-rated ammo lockers can endure intense heat for extended periods and usually come with fire ratings that indicate how long they can withstand a certain temperature without the inside getting too hot.

When ammunition burns, it can “cook off,” meaning the heat can cause the gunpowder inside the bullets to ignite. However, it’s important to note that modern ammunition is quite stable and doesn’t easily explode in a fire.

Best Ammo Storage Practices

There’s more to storing ammo than just tucking it away in a corner. Let’s dive into some essential tips that will keep your ammunition in top shape for when you need it.

Keep Ammo Labeled

The first thing you should do is make sure all your ammo is labeled. This helps you quickly identify the type of ammo you have and its intended firearm. You can do this in two ways:

Put a label on the place where you keep your ammo. Each label should say which gun the ammo is for.
or
Keep the ammo in its original box, which already has a label from the manufacturer. This label tells you when the ammo was made, what kind it is, and other important details.

Use Desiccant Packs or Silica Gels

To keep your ammo dry, you can use desiccant packs or silica gels. These things take in moisture, which keeps your ammo from getting wet and rusty. You can put them in the same can or box as your ammo.

Invest in Military Ammo Cans for Outdoor Storage

Military ammo cans are designed for long-term storage, meaning your ammo will be safe and sound, even if left unused for extended periods. Plus, they’re built for outdoor storage and withstanding extreme heat, snow, rain, and other weather changes. So, if you’re running out of indoor storage space, military ammo cans can be your go-to solution.

Utilize Waterproof Ziplock Bags

Another way to keep your ammo dry is to put it in waterproof ziplock bags. You can put your ammo boxes in these bags before you put them in a can or safe. That way, even if water gets into the can or safe, your ammo will still stay dry.

Maintain an Airtight Seal

It’s important to make sure your ammo is sealed tight. This keeps air and moisture from getting in, which can ruin your ammo over time. Check the seals on your ammo cans, boxes, or safes often and replace them if they’re worn out.

Use Your Oldest Ammo First

You should use your oldest ammo first and replace it with new ammo. This way, you’ll always have fresh ammo when you need it.

Check Your Ammo Frequently

Make sure to check your ammo often for any signs of damage, like rust or discoloration. If you find any ammo that’s damaged, get rid of it safely.
