Can You Store Ammo in a Hot Garage? The Risks and Best Practices
Storing ammunition improperly can lead to serious consequences, from degraded performance to potential safety hazards. The question of whether you can store ammo in a hot garage is a crucial one for firearm owners, and the simple answer is: no, it's generally not recommended. Let's delve into the reasons why.
The Dangers of Heat on Ammunition
Extreme temperatures, particularly heat, can significantly impact the performance and safety of your ammunition. Here's a breakdown of the potential problems:
- Degraded Propellant: Heat can cause the propellant in cartridges to degrade. This degradation can lead to:
- Reduced Velocity: Your rounds may not achieve their intended velocity, impacting accuracy and effective range.
- Increased Pressure: Conversely, degraded propellant can lead to increased chamber pressure, potentially causing damage to your firearm or even resulting in catastrophic failure.
- Squib Loads: In severe cases, the propellant might partially or completely fail to ignite, creating a squib load—a dangerous situation where a bullet is lodged in the barrel. This requires careful and potentially dangerous clearing procedures.
- Case Swelling or Cracking: High temperatures can cause the brass or steel casing of your ammunition to swell or crack. This can hinder proper feeding and chambering in your firearm, again leading to potential malfunctions and safety risks.
- Primer Sensitivity: While less directly affected by heat than the propellant, primers can also be impacted by prolonged exposure to extreme temperatures. This can affect their reliability, making them more prone to misfires or accidental discharges.
Ideal Storage Conditions for Ammunition
To ensure the longevity and safety of your ammunition, store it in a cool, dry, and well-ventilated area. The ideal temperature range is between 50°F and 70°F (10°C and 21°C). Avoid:
- Direct Sunlight: Sunlight's UV rays can degrade the propellant and casing over time.
- Excessive Humidity: High humidity can promote corrosion and rust on the ammunition components.
- Fluctuating Temperatures: Constant temperature changes are more damaging than consistent moderate temperatures.
Alternatives to a Hot Garage
If your garage regularly experiences high temperatures, consider these alternatives for ammo storage:
- Climate-Controlled Storage: A climate-controlled storage unit offers a reliable environment for safeguarding your ammunition.
- Indoor Location: Storing ammunition inside your home, in a cool, dry closet or cupboard, is a much safer option.
- Ammunition Safe: Investing in a dedicated ammunition safe provides security and environmental protection for your ammo.
Conclusion: Prioritize Safety and Longevity
Storing ammunition in a hot garage is a risky practice that can compromise its performance, create safety hazards, and potentially lead to firearm damage or injury. Prioritizing proper storage conditions is crucial for responsible firearm ownership. Always store ammunition according to manufacturer guidelines and prioritize safety above all else. Remember, proper ammunition storage is not just about maintaining its effectiveness but about ensuring the safety of yourself and others.
