10 Smart Uses for a Surplus Ammo Can

Why an ammo can is worth it

Before the uses, it helps to understand why these containers earn their keep. The steel body shrugs off knocks, the latching lid clamps down hard, and the rubber gasket creates a tight seal against water and dust. They stack neatly, which matters when storage space is tight.

You can usually find them at surplus stores and online for a modest price. Look for one with a gasket in good condition, because that seal is what makes the can genuinely weather resistant. A quick wipe of the rubber and a check of the latch is all most cans need before you start filling them.

A few minutes of inspection before you buy saves trouble later. The single most important part is the rubber gasket, since a cracked or missing seal undoes the whole point of the container, so run a finger around it and make sure it is supple and continuous. Check the body for rust holes, test that the latch closes firmly and holds, and open and shut the lid a few times to confirm the hinge is sound. Sizes range from small handgun cans to larger boxes, so picture the job before you buy. One more habit pays off over time. Label every can on the outside with what is inside and the date you packed it. When you own several, clear labels turn a stack of identical green boxes into an organized system you can grab from in seconds, even in low light.

1. A waterproof document and electronics box

The sealed lid makes an ammo can a natural home for paperwork and small electronics you cannot afford to lose. Passports, birth certificates, insurance papers, a backup drive, and a spare phone all stay dry inside.

Add a couple of silica gel packets to soak up any trapped moisture, and keep the can somewhere cool. It is the kind of grab and go protection that keeps your important papers organized in one place you can carry out the door in a hurry.

2. A compact first aid or fire kit

Ammo cans come in handy sizes for building dedicated kits. A smaller can makes a tidy, protected first aid box that keeps bandages and supplies clean and dry. A second can works perfectly as a fire kit.

The hard shell protects fragile contents from being crushed in a closet, a trunk, or a backpack, and the seal keeps matches and tinder dry.

• First aid kit: bandages, gauze, tape, antiseptic, gloves, basic medicines
• Fire kit: waterproof matches, a lighter, a ferro rod, and dry tinder
• Repair kit: tape, cordage, zip ties, and a multi tool

3. A dry food and water cache

The airtight seal that protects ammunition also protects food. An ammo can is a solid home for a small cache of dry staples like rice, beans, oats, and sealed snacks, keeping pests and moisture out.

It is a neat way to rotate a modest reserve without dedicating a whole shelf to it, and the sealed can keeps the contents safe from the damp and pests that ruin food left in flimsy packaging. For the full picture on building and rotating a household supply, see our guide to emergency food and water storage, then use a can or two to keep a portion sealed and portable.

4. A grab and go car emergency kit

An ammo can is ideal for the trunk. It stays put, resists the temperature swings of a parked car better than flimsy plastic, and keeps a roadside kit organized in one sealed package.

Stock it with the essentials for being stuck on the road, and you will have a calm, ready answer to a breakdown or bad weather. This is a natural extension of how to build an emergency kit, sized for the vehicle.

• Flashlight or headlamp with spare batteries
• Jumper cables, a tow strap, and basic tools
• Water, snacks, and a small first aid kit
• A blanket, gloves, and a high visibility vest
• A phone charger and a paper map of your area

5. Seeds, electronics, and small supply storage

Gardeners love ammo cans for seed storage, because the dry, sealed interior keeps seeds viable far longer than a paper packet on a shelf. Drop in a silica gel packet and your seeds stay cool and dry through the off season.

The same logic applies to spare electronics, chargers, matches, candles, and batteries, and any small supply that hates moisture. The closed steel body keeps dust out and adds a layer of physical protection, turning a jumble of loose items into a protected, labeled cache you can find in a hurry.

6. A power outage box you can grab in the dark

Keep one can dedicated to outage gear so you are never digging through drawers by phone light. A headlamp, candles, a lighter, batteries, a power bank, and a battery radio all fit neatly in a single sealed box.

Store it somewhere everyone in the household knows, and label it clearly. When the lights go out, you reach for one can and have what you need, without digging through drawers or hunting for batteries in the dark.
