Can Shotgun Shells Go Bad?
As a shooter, you’ve likely wondered about the shelf life of your shotgun shells. Can they indeed go bad? The answer is yes, but not necessarily in the way you might think. In this article, we’ll dive into the world of shotgun shells and explore the factors that affect their performance over time.
What’s the Shelf Life of Shotgun Shells?
Storage Conditions
Before we dive into the details, it’s essential to understand that storage conditions play a significant role in determining the shelf life of shotgun shells. Temperature, humidity, and exposure to light all impact the longevity of your shells.
| Storage Conditions | Shelf Life (years) |
|---|---|
| Ideal (65°F to 75°F, 40% to 60% humidity, and low light) | 5-10 years |
| Average (normal indoor conditions) | 3-5 years |
| Poor (high temperature, high humidity, and direct sunlight) | 1-3 years |
Physical Integrity
Another critical factor that affects the shelf life of shotgun shells is physical integrity. When a shell is manufactured, it’s designed to withstand specific pressure and stress conditions. Over time, exposure to temperature fluctuations, humidity, and physical handling can cause the shell to deteriorate, leading to compromised performance.
Corrosion and Rust
Corrosion and rust are common issues that can affect shotgun shells, particularly those made of metal. Brass and stainless steel shells are more prone to corrosion than plastic shells. When moisture enters the shell, it can accelerate the corrosion process, compromising the shell’s integrity and potentially causing misfires.
Chemical Degradation
Chemical degradation occurs when the shell’s components break down over time, affecting its performance and reliability. This can be caused by factors such as:
• Age: As shells age, their chemical composition can degrade, leading to reduced reliability.
• Temperature: High temperatures can accelerate chemical reactions, causing the shell’s components to break down faster.
• Humidity: High humidity can accelerate corrosion and chemical degradation.
Signs of Aging Shotgun Shells
Mold and Mildew: Visible signs of mold and mildew on the shell’s surface can indicate the presence of moisture and humidity.
Cracking and Fissuring: Cracks and fissures on the shell’s surface can indicate physical damage and compromised integrity.
Rust and Corrosion: Rust and corrosion on metal shells can indicate exposure to moisture and humidity.
What to Do with Old Shotgun Shells
Inspect and Test
Before using old shotgun shells, it’s crucial to inspect and test them. Check for signs of corrosion, rust, or mold, and perform a pressure test to ensure the shell is still reliable.
Replace or Refurbish
If your shells are showing signs of aging, it’s best to replace them or consider refurbishing them. Refurbishing involves cleaning, drying, and re-coating the shell to restore its integrity.
Conclusion
In conclusion, shotgun shells can indeed go bad over time due to storage conditions, physical integrity, corrosion, and chemical degradation. Regular inspection and testing can help identify potential issues before they become a problem. By understanding the factors that affect the shelf life of your shotgun shells, you can take steps to maintain their performance and reliability. Always prioritize safety when handling and using shotgun shells, and never compromise on the integrity of your equipment.
