If you're a gun owner, you probably have ammunition lying around somewhere. But here's what most people don't realize – storing ammunition properly isn't just about keeping it organized. It's about safety, longevity, and protecting your investment.
I've been around guns long enough to see people store ammo in all kinds of places. Some keep it in plastic bags in the basement, others just toss boxes in a closet. And honestly? That's a recipe for disaster. Improper ammunition storage can lead to corrosion, reliability issues, and safety hazards.
Let me break down the best practices for storing ammunition safely, so you know exactly what you're doing.
Why Ammunition Storage Matters
Ammunition is sensitive to moisture, temperature changes, and humidity. When you expose ammo to these elements, the powder inside degrades, primers can fail, and the rounds become unreliable – or worse, dangerous.
Think about it this way: you spent money on quality ammunition. Why let it go bad? Proper ammunition storage solutions protect your investment and ensure your rounds work when you need them.
Temperature Control is Key
The ideal temperature for storing ammunition is between 50°F and 75°F. Extreme heat causes powder to burn faster, which means inconsistent velocity. Cold temperatures can affect primer sensitivity. Neither situation is good.
If you store ammo in an attic or uninsulated garage, you're fighting a losing battle. That's why a climate-controlled space – like your bedroom, basement, or inside a gun safe – is essential for ammunition storage.
Moisture is Your Enemy
This is the biggest threat to ammunition. Moisture causes rust on brass casings and corrodes primers. I've seen entire boxes of ammo ruined because someone stored them in a damp basement.
Here's what works: keep ammunition in an airtight container with desiccant packets. These moisture-absorbing packets pull humidity out of the container and keep your ammo dry. You can find them at any sporting goods store, and they're cheap.
If you're storing larger quantities of ammunition, invest in a dehumidifier for your storage space. Seriously, it makes a huge difference.
Organization and Accessibility
When you're storing ammunition safely, organization matters too. Keep different calibers separated so you don't accidentally grab the wrong ammo. Label everything clearly – caliber, brand, and date purchased.
This also makes inventory management easier. You'll actually know how much ammo you have instead of discovering surprise boxes months later.
Use a Quality Gun Safe for Ammunition Storage
This is where a good gun safe becomes invaluable. A quality gun safe provides multiple benefits for ammunition storage: temperature stability, moisture protection, security, and organization space.
If you're looking for a gun safe that has excellent ammunition storage capacity and climate control features, you'll want something specifically designed for this. Not all gun safes are created equal when it comes to storing ammunition alongside your firearms.
I recently reviewed a bunch of gun safe options that excel at ammunition storage, and I've got detailed comparisons of gun safes with climate control and moisture management features. Whether you're looking for a compact safe or a larger model, there are solid options available.

Best Practices Summary
Store ammunition in a cool, dry place. Use airtight containers with desiccant packets. Keep it away from direct sunlight. Separate different calibers. Label everything clearly. And most importantly, store ammo in a secure gun safe alongside your firearms.
Proper ammunition storage is simple once you understand the basics. Do it right, and your ammo stays reliable, safe, and ready for years to come.
