The Impact of Temperature on Ammo Storage

If you’re an avid gun enthusiast and you like to store ammunition for long periods, then you must understand the impact of temperature on your ammo storage. Ammo storage is a crucial aspect of gun safety as it helps to maintain the quality and usability of your ammunition. However, it is often overlooked when it comes to ensuring that your firearms are in perfect working condition. This blog post explores the effects of temperature on ammo storage and how it can impact the usability and safety of your ammunition.

Why Temperature Matters

The temperature at which you store your ammunition plays an important role in determining how long your ammo will last. The ideal temperature range for ammo storage is between 50-70 degrees Fahrenheit. The cooler the temperature, the longer the shelf life of your ammunition. Conversely, storing your ammo in hot temperatures can lead to degradation and can reduce the effectiveness of your ammo. When the temperature rises above 100 degrees Fahrenheit, this can cause the cartridges to break down and corrode. As a result, the ammo can become less effective, or even completely unusable.

Humidity is a Killer

Storing your ammo in a humid environment can also have negative impacts on your ammunition. Humidity can cause moisture to build up inside the cartridge, leading to corrosion and rust. This can ultimately result in unstable rounds that can be difficult to fire or even dangerous to use. The ideal humidity range for ammo storage is between 40-50%. Anything above this range can damage and weaken your ammunition.

Storage Duration

The duration of storage is another factor that can impact your ammunition. Regardless of temperature or humidity, ammunition that is stored for a long time can deteriorate over time. This can lead to weakened cartridges that are more prone to malfunction or even fail. To ensure that your ammunition stays in top condition, it’s recommended that you only store it for three to five years depending on the conditions of your storage.

Proper Storage

When storing your ammo, it’s important to consider not only the temperature and humidity levels but also how you store it. To ensure that your ammo remains in good condition, it should be stored in a dry, cool, and dark place. It’s a good idea to store your ammo in a fireproof and waterproof safe, away from direct sunlight. This will help to prevent accidents and ensure that your ammunition is properly stored.


In conclusion, it’s crucial to store your ammunition correctly to ensure your firearms are safe and ready to use when you need them. Consider the temperature, humidity, and duration of storage when storing your ammo. Keep your ammo in a dry, cool, and dark place to prevent degradation and ensure that it remains in top condition. By following these simple steps, you can ensure that your ammunition remains usable for its intended purposes and that you stay safe while using it.
