Can Ammo Be Stored in a Hot Garage? The Risks of Extreme Temperatures on Your Ammunition
Storing ammunition improperly can lead to serious consequences, from degraded performance to potential safety hazards. One common question among gun owners is whether storing ammo in a hot garage is safe. The short answer is: no, storing ammo in a hot garage is not recommended. Let's delve into the reasons why.
The Dangers of Heat on Ammunition
High temperatures significantly affect the chemical composition of ammunition components. Here's a breakdown of the risks:
-
Powder Degradation: Gunpowder is highly sensitive to heat. Prolonged exposure to high temperatures can cause the propellant to decompose, leading to:
- Reduced Velocity: A weaker charge means lower projectile velocity, impacting accuracy and effectiveness.
- Increased Pressure: In some cases, decomposition can lead to increased pressure within the cartridge, potentially causing dangerous malfunctions like bulging cases or even barrel bursts.
- Misfires or Hangfires: Degraded powder may fail to ignite consistently, resulting in misfires or unpredictable hangfires (a delayed ignition).
-
Primer Deterioration: Ammunition primers are also susceptible to heat damage. Extreme temperatures can weaken the primer's sensitivity, potentially resulting in:
- Misfires: The primer may not ignite the powder charge, leading to a complete failure to fire.
- Unsafe Conditions: A compromised primer increases the risk of accidental discharge during handling or loading.
-
Case Corrosion: Heat and humidity, often present in poorly ventilated garages, can accelerate the corrosion of cartridge cases, especially brass cases. This can lead to:
- Difficulty Chambering: A corroded case may not chamber smoothly, leading to jams or malfunctions.
- Weakened Case Integrity: Corrosion weakens the structural integrity of the case, increasing the risk of failure under pressure.
-
Lubricant Breakdown: The lubricants used in ammunition components can break down under high temperatures, leading to increased friction and potentially affecting functionality.
Ideal Storage Conditions for Ammunition
To maintain the integrity and safety of your ammunition, store it in a cool, dry, and well-ventilated location. The ideal temperature range is between 35°F and 70°F (2°C and 21°C). Avoid direct sunlight and fluctuating temperatures.
Alternative Storage Solutions
If your garage experiences extreme temperatures, consider alternative storage solutions:
- Indoor Storage: Storing ammo inside your home in a climate-controlled area is the best option.
- Ammunition Safe: A dedicated ammunition safe can provide protection against temperature fluctuations and unauthorized access.
- Cooler Storage: In extreme climates, a small, insulated cooler can help moderate temperatures.
Conclusion: Prioritize Safety
Storing ammunition in a hot garage is a risky practice that can compromise the safety and effectiveness of your ammunition. Prioritizing proper storage conditions is crucial for maintaining the integrity of your rounds and ensuring safe handling. Always prioritize safety when handling firearms and ammunition. Remember, responsible gun ownership includes responsible ammunition storage.
