Can Ammo Go Bad?
When it comes to storing ammunition, many gun owners wonder if their rounds can go bad over time. The answer is yes, but it’s not as simple as just saying "yes" or "no." The condition and quality of ammunition can degrade over time, affecting its performance and reliability. In this article, we’ll explore the factors that can affect the shelf life of ammunition and what you can do to ensure your rounds remain in good condition.
What is the Shelf Life of Ammunition?
The shelf life of ammunition varies depending on several factors, including the type of ammunition, storage conditions, and manufacturer’s recommendations. Generally, most ammunition has a shelf life of 5-10 years, but this can range from 2-20 years or more. Here’s a breakdown of the typical shelf life for different types of ammunition:
| Type of Ammunition | Typical Shelf Life |
|---|---|
| Rifle Cartridges | 5-10 years |
| Pistol Cartridges | 5-10 years |
| Shotgun Shells | 5-10 years |
| Specialty Ammunition (e.g., Tracer, Incendiary) | 2-5 years |
| Smokeless Powder | 5-10 years |
| Black Powder | 2-5 years |
Factors Affecting Ammunition Shelf Life
Several factors can affect the shelf life of ammunition, including:
• Temperature: Extreme temperatures can cause chemical reactions that degrade the ammunition. High temperatures can cause the propellant to break down, while low temperatures can cause the lubricants to become brittle.
• Humidity: High humidity can cause corrosion and rust on metal components, while low humidity can cause the propellant to dry out.
• Light: Direct sunlight can cause the propellant to degrade and the primers to become sensitive.
• Storage Conditions: Ammunition stored in a damp, dirty, or poorly ventilated environment is more likely to degrade faster.
• Manufacturer’s Recommendations: Some manufacturers may have specific storage recommendations for their ammunition, which should be followed to ensure optimal shelf life.
Signs of Degraded Ammunition
If your ammunition is stored improperly or has exceeded its shelf life, it may exhibit the following signs of degradation:
• Corrosion: Rust or corrosion on metal components, such as casings or primers.
• Discoloration: Changes in color or texture of the propellant or primers.
• Moisture Absorption: Increased moisture absorption, which can cause the ammunition to become brittle or develop cracks.
• Reduced Velocity: Reduced velocity or accuracy when firing degraded ammunition.
• Increased Misfires: Increased misfires or failure to fire due to degraded primers or propellant.
How to Store Ammunition
To ensure your ammunition remains in good condition, follow these storage guidelines:
• Store in a Cool, Dry Place: Ammunition should be stored in a location with a consistent temperature between 60°F and 80°F (15°C and 27°C) and humidity below 60%.
• Use Ammunition Cases or Containers: Store ammunition in its original packaging or use specialized cases or containers designed for storing ammunition.
• Keep Away from Direct Sunlight: Store ammunition away from direct sunlight to prevent degradation.
• Avoid Moisture: Store ammunition in a dry environment to prevent moisture absorption.
• Check Ammunition Regularly: Regularly inspect your ammunition for signs of degradation and discard any that show signs of damage or degradation.
Conclusion
In conclusion, while ammunition can go bad over time, proper storage and handling can help extend its shelf life. By understanding the factors that affect ammunition shelf life and following proper storage guidelines, you can ensure your rounds remain in good condition and perform reliably when needed. Remember to check your ammunition regularly for signs of degradation and discard any that show signs of damage or degradation.
