This video explains that ammunition does not truly expire if stored properly, with tests suggesting longevity of up to 100 years in ideal conditions. While metal cases may discolor or corrode due to oxidation and moisture, this often does not affect functionality if the primer and powder remain dry. Proper storage in sealed containers can mitigate these issues, though cosmetic changes are common.

Quick Summary

Ammunition does not truly expire if stored correctly. While cosmetic issues like case discoloration or corrosion can occur due to oxidation and moisture, the ammunition often remains functional as long as the primer and powder stay dry. Tests suggest ammunition can last for decades, even up to 100 years, in ideal conditions.

Frequently Asked Questions

Can ammunition really expire or go bad?

Ammunition does not truly expire if stored correctly. While cosmetic issues like case discoloration or corrosion can occur due to oxidation and moisture, the ammunition often remains functional as long as the primer and powder stay dry. Tests suggest ammunition can last for decades, even up to 100 years, in ideal conditions.

What are the signs that ammunition might be degraded?

Signs of degradation include metal cases becoming discolored, tarnished, dull, or showing green or black spots, and sometimes visible corrosion. Paper packaging may also change color due to moisture. However, these are often cosmetic and may not impact the ammunition's ability to fire.

How should ammunition be stored to ensure longevity?

To ensure longevity, ammunition should be stored in dry conditions, ideally in sealed containers. Using desiccants can help absorb any residual moisture. Avoiding extreme temperature fluctuations and humidity is crucial for preserving the integrity of the primer and powder.

Does corrosion on ammunition mean it won't fire?

Not necessarily. While corrosion on the exterior of the case is common, it often cleans up easily. As long as the internal components like the primer and powder have remained dry and unaffected by moisture, the ammunition is likely still viable and will function.
