Best Ammo Cans
A good ammo can protects your ammunition from moisture, dust, and impact while keeping your storage area organized. Whether you need a heavy-duty metal can, a lightweight polymer option, or a crate for bulk storage, choosing the right one depends on your specific needs.
Below are some of the best ammo cans available, selected for durability, practicality, and overall value. Each option stands out for its design, storage capacity, and ability to keep your ammo secure.
1. Fortress Metal Ammo Can
- Durable steel construction ensures long-lasting use.
- Airtight and waterproof rubber seal protects ammo from moisture.
- Stackable design maximizes storage space.
Pros
Cons
I picked the Fortress Metal Ammo Can as the “Best Overall” because its rugged steel build can take a beating and keep going. For someone like me, whether I’m shooting at the range or prepping for the future, this can’s toughness is a game-changer. It’s the kind of gear that promises to protect my ammo for the long haul without showing signs of wear.
The airtight and waterproof rubber seal impresses me every time—it keeps moisture out no matter how nasty the weather gets. I love how the stackable design lets me pile up multiple cans without them tipping over, saving space in my storage setup. It’s a smart, practical feature that fits my style perfectly.
That heavy-duty latch snaps shut tight, giving me confidence nothing’s slipping out, and I can’t get enough of the military vibe it brings. It’s got a classic look with modern reliability, making it handy for more than just ammo—like stashing tools or small gear. Versatility like that keeps it at the top of my list.
I see this can as a go-to for long-term storage or whatever else I need to tuck away, delivering quality that’s hard to top. The only catch is the weight—it’s heavier than plastic options, which can feel like a chore when I’m lugging it around. That’s the one hiccup I’d note.
2. Sheffield Ammo Storage Box
- Affordable price makes it accessible for bulk purchases.
- Lightweight plastic build enhances portability.
- Water- and dust-resistant gasket keeps contents safe.
- Many colors available.
Pros
Cons
I went with the Sheffield Ammo Storage Box as the “Best Budget Option” because it delivers solid value without breaking the bank. Made from lightweight plastic, it’s easy for me to carry to the range or stash in tight spots, and the water- and dust-resistant gasket keeps my ammo safe from the elements. It’s a no-nonsense choice that suits my need for affordable, functional storage, especially when I’m buying in bulk or just starting out.
The stackable design with its interlocking base-to-lid system catches my eye—it stays stable when I pile a few together, which is great for keeping my gear organized. That compression-fit lid with a rubber seal gives me confidence that my 9mm or .30 caliber rounds won’t get wrecked by a little rain or dust. Plus, knowing it’s made in the USA adds a layer of trust in its quality for the price.
It’s got a straightforward, compact build that I find perfect for slipping into a range bag or keeping in the garage. The three locking options, including a metal hasp, let me secure it against prying hands, which is a nice perk for something so budget-friendly. For me, it’s all about getting the job done without fancy extras—just reliable storage that won’t empty my wallet.
This box handles the basics well, and I can see it working for tools or emergency supplies too, not just ammo. It’s a practical pick that punches above its weight in the budget category. The one thing that nags at me, though, is that the plastic feels a bit flimsy—it might crack if I drop it loaded up, which could be a letdown.
3. MTM AC4C 4-Can Ammo Crate
- Ideal for separating ammo types or calibers.
- Four detachable 30-caliber cans for versatile organization.
- Rugged polypropylene build withstands tough handling.
- O-ring seals on each can keep ammo dry and secure.
Pros
Cons
I chose the MTM AC4C 4-Can Ammo Crate as the “Best for Organization” because it’s a game-changer for keeping my ammo sorted and ready. With four detachable 30-caliber cans nestled in a rugged polypropylene crate, it lets me separate my 9mm, .45, .223, or whatever else I’ve got on hand without mixing them up. The O-ring seals on each can keep everything dry, which is a must when I’m storing ammo long-term or heading out in unpredictable weather.
The stackable crate with its tie-down points really stands out to me—it’s perfect for tossing in the truck or securing to an ATV when I’m on the move. Each can’s double latches snap shut tight, and the whole setup feels sturdy enough to handle rough treatment without falling apart. I appreciate how it’s made in the USA, too; that gives me some extra confidence in its build quality for the price.
For me, this crate’s all about versatility and ease—I can grab just one can for a quick range trip or haul the whole thing when I’m stocking up. It’s not just ammo, either; I could see using it for tools or small gear if needed. The design keeps everything tidy and accessible, which fits how I like to roll when I’m shooting or organizing my stash.
This thing’s a solid pick for staying on top of my ammo game, and I’d recommend it to anyone who hates digging through a jumbled mess. The one downside that hits me, though, is that the individual cans can tip over if I pull them out of the crate and set them down solo—kind of annoying when I’m in a hurry.
4. MTM ACR7-18 Ammo Crate
- Massive 65-lb capacity for bulk ammo or gear storage.
- Water-resistant O-ring seal protects against humidity.
- Stackable with molded ridges for stable piling.
- Double padlock tabs add security for valuable contents.
Pros
Cons
I named the MTM ACR7-18 Ammo Crate the “Best Large Crate” because it’s a beast when it comes to hauling bulk ammo or gear, holding up to 65 pounds with ease. Made from tough polypropylene, it’s got two strong side handles that make carrying that weight manageable, whether I’m loading it into the truck or stacking it in the garage. The water-resistant O-ring seal keeps my ammo dry in damp conditions, which is clutch for long-term storage or outdoor trips.
The stackable design with molded ridges really works for me—it lets me build a tower of crates without worrying about them toppling over. Those four tie-down points on the sides are a nice touch too, perfect for securing it to an ATV or boat when I’m out in the field. Double padlock tabs and sturdy latches add a layer of security, so I know my stuff’s safe from prying hands. Plus, it’s made in the USA, which gives me some extra faith in its build.
For me, this crate’s all about capacity and toughness—I can cram in boxes of 12-gauge shells, rifle rounds, or even survival gear without blinking. It’s versatile enough to double as a dry storage box for camping or emergencies, not just ammo. The size (17.2″ x 10.7″ x 9.2″ outside) gives me plenty of room to play with, making it a go-to for big hauls or serious prepping.
This crate’s a solid win for anyone needing to store or move a lot at once, and I’d pick it again for its sheer utility. The one thing that gets me, though, is that the handles can feel strained when it’s fully loaded—pushing that 65-pound limit might wear them down over time.
5. MTM Tactical Magazine Can
- Pre-cut foam padding securely holds magazines.
- Designed for popular handgun mags (e.g., 9mm, .45).
- Water-resistant O-ring seal protects loaded mags.
- Stackable with tie-down points for range or travel.
Pros
Cons
I selected the MTM TMCHG Tactical Magazine Can as the “Best for Magazines” because it’s tailor-made for keeping my handgun mags organized and secure. The pre-cut foam padding locks in up to 16 single-stack 1911 mags or a mix of double-stack 9mm and .45 ACP mags, keeping them snug and rattle-free whether I’m headed to the range or stashing them at home. The water-resistant O-ring seal is a big plus, ensuring my loaded mags stay dry in humid or rainy conditions, which matters when I’m out and about.
The stackable design with tie-down points really appeals to me—it stacks neatly with my other gear and stays put in the truck bed when I’m rolling out. Those double latches snap tight, and the two padlock tabs let me lock it down if I need extra security, like when I’m storing it somewhere sketchy. Being made in the USA by MTM, a brand I trust, adds some reassurance that it’s built to last through rough handling.
For me, this can’s all about convenience and protection—I can grab it and go without worrying about my mags banging around or getting damaged. It’s not just for range days, either; I could see it holding spare mags in a go-bag or even small tools if I get creative. The dark earth finish gives it a tactical edge that matches my vibe, making it a practical and sharp-looking addition to my setup.
This can’s a winner for keeping my handgun mags in check, and I’d pick it up again for how well it delivers on its promise. The one thing that bugs me, though, is that the foam can compress over time with heavy use, which might loosen the fit for my mags down the line.
How We Tested the Ammo Cans
We selected a range of popular ammo cans and evaluated them for overall build quality, protection, and ease of use. Each can was assessed for durability, resistance to moisture, and how well it kept ammo secure in different conditions. While we didn’t subject them to extreme torture tests, we focused on real-world use to determine which options are worth considering.
When choosing an ammo can, here are key factors to look for:
- Material – Steel offers maximum durability, while polymer cans are lightweight and resistant to rust.
- Seal Quality – A good rubber gasket keeps out moisture and dust.
- Latch Strength – A solid latch ensures the can stays closed, even when dropped.
- Capacity – Consider the size based on the amount and type of ammo you need to store.
- Stackability – Flat-top designs make storage more efficient.
- Portability – Sturdy handles help with transport, especially for heavier loads.
Each ammo can in this guide was reviewed with these factors in mind to help you choose the best option for your storage needs.
Tips on Storing Ammo Properly
Proper ammo storage is essential for maintaining performance and longevity. Poor storage conditions can lead to corrosion, primer degradation, and inconsistencies in performance. Whether you’re storing ammo for self-defense, training, or long-term preparedness, following best practices will help keep your rounds in top condition.
Here are key tips for proper ammo storage:
- Use Airtight Containers – Ammo cans with a rubber gasket create a tight seal that keeps out moisture and dust. This helps prevent corrosion and keeps primers and powder from degrading.
- Control Humidity – Store ammo in a cool, dry place with low humidity. Using desiccant packs inside your ammo cans helps absorb excess moisture and reduces the risk of rust or corrosion.
- Avoid Extreme Temperatures – Heat and cold can affect the stability of gunpowder and primers. Store ammo in a climate-controlled space away from direct sunlight, heaters, or freezing conditions.
- Keep Ammo Off the Floor – Storing ammo on shelves or in cabinets reduces exposure to temperature changes and potential flooding. This is especially important in basements or garages.
- Label and Rotate Stock – Mark ammo cans with the caliber and purchase date. Use older ammo first to keep your supply fresh and prevent long-term degradation.
- Store Away from Chemicals – Keep ammo away from cleaning solvents, gasoline, or other corrosive substances that could weaken casings or primers.
- Secure Your Storage Area – If you have a large ammo supply, consider locking storage solutions to prevent unauthorized access. A locking cabinet or safe adds an extra layer of security.
Taking the time to store your ammo correctly ensures it will be ready when you need it. By keeping moisture, temperature fluctuations, and contaminants under control, you can maximize the shelf life and reliability of your ammunition.
