This guide details expert techniques for long-term ammunition storage, emphasizing the superiority of metal ammo cans over plastic ones. It covers optimal packing strategies for various calibers, the crucial role of desiccants for moisture control, and proper maintenance of rubber seals using silicone grease to ensure longevity and reliability of stored ammunition.

Quick Summary

Metal ammo cans are superior for long-term ammunition storage due to their durability and reliable watertight seals, unlike flexible plastic cans. Protect your ammo by using rechargeable desiccants to control moisture and applying 100% silicone plumber's grease to rubber seals, avoiding petroleum-based products that degrade rubber.

Frequently Asked Questions

Why are metal ammo cans better than plastic for long-term storage?

Metal ammo cans are preferred for long-term storage because they offer superior seals and durability. They are less prone to breaking if dropped and provide a more reliable watertight seal compared to plastic alternatives, which can flex and compromise their integrity.

How can I protect my ammunition from moisture during long-term storage?

To protect ammunition from moisture, use metal ammo cans with good seals and include rechargeable desiccant packs. These packs absorb excess humidity. Additionally, apply silicone plumber's grease to the can's rubber seals to maintain their condition and ensure a watertight closure.

What is the best way to store different calibers of ammunition long-term?

For common calibers like 9mm and 5.56x45, pack .30 caliber metal cans with approximately 1,000 loose rounds. For mixed or specialty calibers like .308 or .300 Blackout, keep the ammo in its original boxes inside the metal cans for easier identification, even though it takes up more space.

What should I avoid when maintaining ammo can seals?

Avoid using petroleum-based products like WD-40 or PB Blaster on the rubber seals of ammo cans. These products can degrade the rubber over time, leading to cracks and a compromised seal. Instead, use 100% silicone plumber's grease.
