After years of perfecting ammunition storage and selling over 35,000 cases to shooters across America, we've learned exactly what makes the perfect ammo case. Whether you're a competitive shooter, hunter, or recreational target shooter, proper ammunition storage isn't just about organization—it's about protecting your investment and ensuring peak performance when it matters most.

Why Proper Ammo Storage Matters More Than Ever in 2025

With ammunition prices still elevated from pre-2020 levels and availability remaining unpredictable, every round counts. The average shooter now spends $1,200-$2,500 annually on ammunition—that's a significant investment that deserves proper protection.

But here's what most people don't realize: improper storage can degrade your ammunition in as little as 6 months, especially in humid climates. Moisture exposure causes:

  • Primer deterioration - Leading to misfires and dangerous hangfires
  • Powder degradation - Resulting in inconsistent velocities and accuracy issues
  • Case corrosion - Causing feeding problems and potential chamber damage
  • Bullet oxidation - Affecting ballistic performance and barrel wear
💡 Pro Tip from Our Range Masters

Store your ammunition at 65-70°F with humidity below 50%. Our cases maintain these conditions naturally through their airtight seal and optional ARIDZONE moisture control system.

The 7 Costly Mistakes Gun Owners Make with Ammo Storage

1. Using Original Cardboard Boxes

Cardboard absorbs moisture like a sponge. In humid environments, cardboard boxes can increase internal humidity by up to 30%, accelerating ammunition degradation.

2. Mixing Different Calibers

We've seen it at the range—grabbing the wrong caliber in a critical moment. Our foam inserts keep each caliber separated and clearly organized.

3. Storing in Basements or Garages

Temperature fluctuations in these areas create condensation inside non-sealed containers. Our IP67 rating means complete protection from moisture infiltration.

4. Using Metal Ammo Cans Without Foam

Metal-on-metal contact causes primer damage and case deformation. Our PROFoam system cradles each round individually.

5. Ignoring TSA Regulations

Improper cases lead to confiscation at airports. All Evergreen cases are TSA-approved and ATA-300 rated for air travel.

6. Buying "Waterproof" Cases That Aren't IP-Rated

True waterproofing requires IP67 certification—tested at 1 meter underwater for 30 minutes. Anything less is just water-resistant.

7. Skipping Security Features

Unsecured ammunition is a liability. Our keyed TwistLock latches keep children and unauthorized users out.

Special Feature: ARIDZONE Technology

Our Pro models include ARIDZONE moisture control cartridges—military-grade desiccants that actively absorb humidity. When the beads turn magenta, simply replace the cartridge (2 included with each case). This feature alone has saved customers thousands of dollars in ammunition that would have otherwise degraded.

TSA-Approved: Flying with Ammunition Made Simple

One of the biggest advantages our customers report is the ability to travel worry-free with their ammunition. Here's what you need to know:

TSA Requirements for Ammunition:

  • Must be in checked baggage only (never carry-on)
  • Must be in a hard-sided, locked container
  • Maximum of 11 pounds per passenger
  • Must be for personal use

Every Evergreen case exceeds these requirements with:

  • ATA-300 certification for airline travel
  • Integrated lock eyelets for TSA-approved locks
  • Crushproof polycarbonate construction
  • Clear labeling areas for declaration
✈️ Travel Tip

Print a copy of TSA regulations and keep it with your case. Some agents aren't familiar with ammunition transport rules, and having the official guidelines speeds up check-in.
