The Ultimate Buying Guide for Ammo Storage Containers
Storing ammunition safely is super important. You need the right container to protect your valuable rounds from damage, moisture, and accidents. This guide helps you pick the best ammo storage box for your needs.
Key Features to Look For
When shopping for an ammo can, check these features first. They make a big difference in how well your ammo stays safe.
1. Water Resistance and Seals
- Gasket Seal: Look for a rubber or foam ring around the lid. This seal keeps water and humidity out. A good seal means your ammo stays dry.
- Watertight Rating: Some cans have an IP rating (like IP67). Higher numbers mean better protection against water.
2. Durability and Construction
- Strong Latches: The clips that hold the lid shut must be tough. Weak latches can pop open, letting moisture in.
- Hinges: Heavy-duty hinges last longer than flimsy ones.
3. Portability and Size
- Handles: A strong handle makes carrying heavy boxes easier.
- Stackability: If you have many cans, boxes that stack neatly save space in your storage area.
- Capacity: Decide how much ammo you need to store. Cans come in sizes for holding 50 rounds up to bulk storage.
Important Materials Matter
The material of the container affects its strength and how long it lasts.
Plastic vs. Metal
- Polymer (Heavy-Duty Plastic): Modern plastic ammo cans are often lighter and resist rust completely. They are great for general storage and transport.
- Steel (Metal): Traditional military-style cans are made of steel. They offer excellent crush resistance. However, steel cans can rust if the paint chips or if they are stored in very damp places.
Factors That Improve or Reduce Quality
Not all ammo cans are made equal. Some small details really change the quality.
Quality Boosters
- Desiccant Slots: The best cans often have a spot inside to place silica gel packets. These packets soak up extra moisture, keeping the environment perfectly dry.
- Pressure Relief Valve: This feature lets air escape if the temperature changes a lot (like moving from a cold basement to a hot car). This prevents the can from being hard to open or damaging the seal.
Quality Reducers
- Thin Plastic: If the plastic feels thin or bends easily when squeezed, it offers poor protection against impacts.
- Poor Hinge Attachment: If the hinges look stapled or weakly molded, they will likely break quickly.
User Experience and Use Cases
How you plan to use the container should guide your choice.
For the Range Bag
If you move ammo frequently, choose smaller, lighter polymer containers. They fit easily into your range bag and are simple to carry.
For Long-Term Storage
For deep storage in a safe or bunker, look for large, extremely durable metal cans or high-grade polymer boxes with excellent gaskets. These protect ammo for years.
For Different Calibers
Remember that different calibers need different box sizes. Storing 9mm rounds requires less space than storing large .308 rifle ammunition. Measure your longest cartridge before buying a container.
10 Frequently Asked Questions (FAQ) About Ammo Storage Containers
Q: Do I really need a special ammo container?
A: Yes. Regular plastic bins do not keep moisture out. Moisture ruins gunpowder and causes corrosion on brass casings.
Q: Can I store different types of ammo in the same can?
A: You can, but it is safer to separate them by caliber. This prevents mistakes at the range.
Q: How often should I check my stored ammunition?
A: Check your containers every six months to a year. Look for signs of rust or moisture intrusion.
Q: Are plastic ammo cans safe for long-term storage?
A: High-quality polymer cans are very safe. They never rust, which is a big advantage over steel over many decades.
Q: What is a desiccant packet, and why do I need one?
A: A desiccant packet (like silica gel) absorbs humidity inside the can, ensuring the air around your ammo stays very dry.
Q: Can heat damage stored ammunition?
A: Extreme heat can degrade the powder faster. Store cans in a cool, dark place, away from direct sunlight or heat sources.
Q: Should I keep the original cardboard boxes inside the ammo can?
A: No. The cardboard takes up space and can absorb moisture. Remove the ammo from the cardboard and place it directly into the can, perhaps using foam dividers.
Q: What does an airtight seal mean for ammo?
A: An airtight seal stops air and water vapor from entering the container, which keeps the gunpowder stable for a longer time.
Q: Are military surplus (surplus) ammo cans a good deal?
A: Surplus cans are usually very strong metal. Check them carefully for rust or damaged gaskets before buying them for long-term use.
Q: How do I clean the inside of an old ammo can?
A: Wipe the inside with a dry cloth. If you see residue, use a very small amount of rubbing alcohol and let it air dry completely before putting ammo back inside.
