The Essential Ammo Storage Can Buying Guide
Keeping your ammunition safe, dry, and organized is super important for any shooter. Ammo storage cans are the tough boxes designed for just this job. Choosing the right one protects your valuable rounds from rust, moisture, and accidents. Here is what you need to know before you buy.
Key Features to Look For
Good ammo cans share a few must-have features. These features keep your ammo in top shape for years.
1. Watertight Seals
The most important feature is a strong seal around the lid. Look for cans that have a thick rubber or silicone gasket. This gasket squeezes tight when you close the lid. It keeps rain, humidity, and spills out. A dry round is a reliable round.
2. Strong Latches
The latches must lock the lid down firmly. Most quality cans use heavy-duty metal clasps. Test them in your mind: Do they look like they will hold up if the can falls? Simple, strong latches are better than complicated ones that can break.
3. Stacking Ability
If you own a lot of ammo, you will want cans that stack neatly. Look for cans with ridges or grooves on the top and bottom. These lock together, saving space in your safe or closet.
4. Carrying Handle
A solid, often hinged, handle makes moving heavy cans easy. Make sure the handle feels secure, even when the can is full of heavy bullets.
Important Materials Matter
What the can is made of directly affects how long it lasts and how well it protects your ammo.
- Steel (The Standard): Most classic ammo cans are made from heavy-gauge steel. Steel offers great physical protection against bumps and crushing. Good steel cans usually have a tough, baked-on paint finish (like Olive Drab green) to stop rust.
- Plastic (Polymer): Newer, lighter options use high-density polymer plastic. These are great because they will never rust. However, very cheap plastic can become brittle over time, especially in extreme cold or heat. Look for thick, rugged plastic designed for outdoor use.
Factors That Improve or Reduce Quality
Not all cans are created equal. A few details separate the best from the rest.
Quality Boosters:
- Thick Metal Gauge: Thicker steel means better dent resistance.
- Removable Gasket: A gasket you can take out for cleaning helps maintain the seal over time.
- Desiccant Holders: Some premium cans have a small compartment inside for silica gel packs (desiccant), which actively pull moisture out of the air inside the can.
Quality Reducers:
- Thin Walls: If the metal feels flimsy when you press it, it won’t protect your ammo during rough handling.
- Poor Seams: Check where the metal pieces are joined. Welds or seams that look weak are potential entry points for water vapor.
- Cheap Latches: If the latches are thin metal or plastic, they might bend or snap easily.
User Experience and Use Cases
How you plan to use the can affects your best choice.
For Long-Term Storage:
If you plan to put the ammo away for five years or more, choose the heavy-duty steel cans with excellent gaskets. These offer the best airtight seal against long-term humidity changes. You might want a larger .50 caliber size for maximum capacity.
For Range Trips:
For taking ammo to the shooting range, lighter plastic cans are often better. They are easier to carry when full, and they resist rust if you leave them briefly in the rain on the firing line. Make sure they still have strong handles and good seals.
Organization:
Consider buying cans in different, standard sizes (like 20mm, .50 cal, 30 cal). This standardization helps you organize different types of ammunition efficiently.
10 Frequently Asked Questions (FAQ) About Ammo Storage Cans
Q: What is the standard color for ammo cans?
A: The most common color is Olive Drab (OD) green. This color was traditionally used by the military.
Q: Can I store other things besides ammo in these cans?
A: Yes! Because they are waterproof and airtight, they make excellent dry storage for tools, electronics, important papers, or survival gear.
Q: Do I need to put anything else inside the can with my ammo?
A: It is highly recommended. Adding desiccant packs (silica gel) inside the can helps control the moisture level, which is the biggest enemy of stored ammunition.
Q: Are plastic ammo cans as good as metal ones?
A: High-quality plastic cans are very good for moisture resistance and are lighter. However, metal cans offer superior protection against crushing or impact damage.
Q: How long will ammunition last inside a good storage can?
A: Stored correctly in a cool, dry place, quality ammunition can last for decades, sometimes even longer, inside a proper sealed can.
Q: What does the size designation (like .50 cal) refer to?
A: The size refers to the original military round the can was designed to hold. A .50 cal can is generally the largest standard box size.
Q: Can I paint my ammo can a different color?
A: Yes, you can paint them. Painting can actually help protect the original finish, but make sure you use a paint that sticks well to metal, like an enamel or military-style spray paint.
Q: Will storing ammo in a metal can attract lightning?
A: No. A small metal box does not increase your risk of being struck by lightning. Store them safely inside a building or a grounded metal safe.
Q: How do I know if the rubber seal is failing?
A: If you can easily squeeze the lid down without much resistance, or if you see cracks or dryness in the rubber gasket, it needs replacing.
Q: Should I store the cans on a concrete floor?
A: It is better to elevate them slightly. Concrete floors can sometimes wick moisture up from the ground, so placing cans on a wooden shelf or pallet is safer for very long-term storage.
