This video explains that ammunition does not truly expire if stored properly, emphasizing the importance of keeping it dry. While metal components like brass cases can discolor and corrode due to oxidation, this typically does not affect the functionality of the primer or powder. The speakers share personal anecdotes and cite Army testing suggesting ammunition can remain viable for up to 100 years under ideal conditions (dry, stable temperature).

Quick Summary

Ammunition does not truly expire if stored correctly. While brass cases can discolor or corrode due to oxidation, this is usually cosmetic and doesn't affect functionality. Moisture is the primary factor that degrades ammo, compromising the primer and powder. Proper storage in dry, stable conditions can allow ammunition to remain viable for decades, potentially up to 100 years.

Frequently Asked Questions

Does ammunition really expire or go bad over time?

Ammunition does not truly expire if stored correctly. While external components like brass cases can discolor or corrode due to oxidation, this typically doesn't affect the primer or powder. Moisture is the main enemy, degrading these critical components and rendering the ammo unreliable.

What are the signs that ammunition might be compromised?

Signs of compromised ammunition include visible corrosion on the casing, which can appear as black spots or a fuzzy substance. Internally, moisture can damage the primer and powder, leading to misfires or inconsistent performance. However, cosmetic tarnish on brass is usually not a functional issue.

How should ammunition be stored to ensure it lasts as long as possible?

The key to long-term ammunition storage is keeping it dry and in a stable temperature environment. Using sealed containers, potentially with desiccants to absorb moisture, is highly recommended. Avoid storing ammo in damp or uncontrolled areas like uninsulated garages or sheds.

Can old ammunition still be fired safely and effectively?

Yes, old ammunition can often still be fired safely and effectively, provided it has been stored properly and kept dry. Army tests suggest ammunition can last up to 100 years under ideal conditions. However, it's always wise to inspect it for any signs of significant corrosion or primer damage before use.
