The Invisible Enemy
If you’ve ever opened a factory box of ammunition or a surplus ammo can, you’ve likely
seen a small white packet labeled “DESICCANT: DO NOT EAT.” Most shooters toss
these aside without a second thought, but in the world of long-term readiness, these
little packets are your front-line defense against the single greatest threat to your brass:
Moisture.
Why Ammo Hates Humidity
Ammunition is a precise chemical and mechanical assembly. When high humidity
(above 50%) is allowed to sit on your stash, several things happen:
- Oxidation: The copper in your brass cases reacts with oxygen and moisture,
creating that green “corrosion” (verdigris) that can cause feeding failures. - Primer Degradation: While modern primers are incredibly stable, extreme
moisture over years can penetrate the seal and lead to “click-no-bang” hang-
fires. - Case Integrity: Significant corrosion can weaken the case wall, leading to
catastrophic failures during the high-pressure event of firing.
How Silica Gel Works (And Why Yours Might Be Dead)
Silica gel is a “desiccant”—a substance that pulls water molecules out of the air and
holds them in its porous structure.
The Problem: Those little packets that come in your shipping boxes are often
“saturated” by the time they reach you. Like a sponge that is already full of water, a
saturated silica packet cannot protect your ammo. If the packet feels “clumpy” or hard
rather than like loose sand, it is likely finished.
The “Freedom First” Storage Protocol
To ensure your investment stays factory-fresh for 10, 20, or 30 years, we recommend
the following protocol:
1. Use an Airtight Seal: Silica gel only works in a closed system. Use steel
M2A1 ammo cans with a healthy rubber gasket. If air can get in, your silica gelwill saturate within days.
2. The “Rule of Weight”: For every cubic foot of storage space, you need
approximately 5-10 grams of active silica gel.
3. Use Indicating Silica: We recommend using “Indicating” beads. These
change color (usually from Blue to Pink or Orange to Green) when they are full of
moisture. This takes the guesswork out of your readiness audit.
4. Recharge, Don’t Replace: Most high-quality silica units can be “recharged” in
a standard oven at 250°F for a few hours. This drives the moisture out and
makes the unit brand new again.
Summary: Protecting the Crate
When you buy a crate of Freedom First ammo, you are buying peace of mind. By
spending $15 on a rechargeable desiccant unit and using proper airtight cans, you are
ensuring that the rounds you buy today will perform flawlessly whenever you—or the
next generation—need them.
