The Essential Ammo Box Buying Guide

An ammo box is a tough container. It keeps your ammunition safe and dry. It also helps you stay organized. Choosing the right one matters for protection. This guide will help you pick the best box for your needs.

Key Features to Look For

Good ammo boxes share important features. These features protect your valuable rounds.

1. Water Resistance and Sealing
  • Gasket Seal: Look for a rubber or foam seal around the lid. This seal keeps water and moisture out. A tight seal is crucial for long-term storage.
  • Locking Latch System: Strong latches keep the lid shut tight. Four latches are better than two. They create even pressure on the seal.
2. Durability and Construction
  • Hinges: Heavy-duty hinges last longer. Cheap plastic hinges break easily.
  • Handles: A strong, comfortable handle makes carrying heavy boxes easier.
3. Capacity and Organization
  • Size: Boxes come in many sizes. Measure the ammo you store most often. Do you need space for many boxes of 9mm or larger rifle rounds?
  • Stackability: If you have many boxes, ensure they stack securely. This saves shelf space in your storage area.

Important Materials Matter

The material of the box determines how long it lasts and how well it protects.

Metal vs. Plastic

Historically, metal boxes were the standard. Modern plastic boxes offer great alternatives.

  • Steel (Metal Boxes): These are very strong. They resist crushing well. However, metal rusts if the paint chips or moisture gets inside. You must keep metal boxes dry.
  • Polypropylene (Plastic Boxes): High-density plastic is lighter than steel. Good plastic resists cracking, even in cold weather. Most modern, high-quality boxes use this material.
Hardware Quality

Check the metal parts, like latches and hinges. Stainless steel hardware resists rust better than regular steel. This small detail boosts the box’s lifespan greatly.

Factors That Improve or Reduce Quality

Not all ammo boxes are created equal. A few details separate the great boxes from the weak ones.

Quality Boosters:
  • UV Resistance: If you store boxes in a garage or shed, sunlight can weaken plastic over time. UV-resistant plastic lasts much longer.
  • Pressure Relief Valve: Some specialized boxes have a small valve. This valve lets air pressure equalize if the box travels on an airplane or changes altitude significantly.
Quality Reducers:
  • Thin Plastic Walls: If the plastic feels flimsy when you press it, it will likely crack under stress.
  • Poorly Fitted Lids: If the lid wobbles when closed, the gasket seal will not work correctly. Water will seep in.

User Experience and Use Cases

Think about how you will use your ammo box.

Storage vs. Transport
  • Long-Term Storage: If the box stays in one place (like a safe or basement), focus on excellent sealing and large capacity. Weight is less of a concern.
  • Transport/Range Days: If you carry the box often, prioritize lighter weight and strong handles. Easy-to-open latches save time at the range.
Other Uses

Ammo boxes are great for more than just bullets. People use them to store tools, first-aid kits, or sensitive documents. Their rugged nature protects whatever you place inside them.


10 Frequently Asked Questions (FAQ) About Ammo Boxes

Q: What is the main difference between a metal and a plastic ammo box?

A: Metal boxes offer superior crush resistance. Plastic boxes are lighter and will not rust, though they can crack if hit very hard.

Q: How important is the rubber gasket seal?

A: The gasket seal is very important. It creates the watertight barrier that keeps humidity and water away from your ammunition.

Q: Can I use an old military surplus ammo can?

A: Yes, surplus cans are often very durable. Check them carefully for rust, especially around the hinges and latch points, before storing valuable ammo inside.

Q: Do I need a padlock hole?

A: A padlock hole allows you to secure the box against unauthorized access. This is a good safety feature, especially if children are around.

Q: How do I check if a plastic box is truly waterproof?

A: After closing the lid, try submerging the closed box in a tub of water for a few minutes. Check inside afterward to see if any moisture entered.

Q: Will extreme cold damage a good plastic ammo box?

A: High-quality polypropylene plastic handles cold well. Very cheap plastic can become brittle and crack in freezing temperatures.

Q: Should I store my ammo in its original cardboard box inside the ammo can?

A: Yes, this is recommended. Storing rounds in their original boxes adds another layer of protection and helps keep them organized inside the larger can.

Q: Are stackable boxes better than non-stackable ones?

A: Stackable boxes save space. They are better if you have many boxes to store on shelves. Ensure the stacking ridges lock together securely.

Q: What does ‘UV resistance’ mean for an ammo box?

A: UV resistance means the plastic resists breaking down when exposed to sunlight. This helps the box last longer if stored outdoors or in a sunny shed.

Q: How often should I inspect my stored ammo boxes?

A: You should check your boxes at least once a year. Look for signs of rust on metal boxes or cracks/seal deterioration on plastic ones.
