If you spend hours at the reloading bench perfecting your loads, the last thing you want is moisture or dust ruining your handcrafted ammunition. Finding the best ammo storage cans for reloaders means looking beyond basic containers to solutions that protect your investment in brass, powder, and primers.
Reloaders have unique storage needs that go beyond what the average shooter deals with. You are not just storing factory ammo. You are managing sorted brass by caliber, keeping track of different load recipes, organizing primers, and protecting finished rounds that took real time and effort to produce. A good ammo can becomes the backbone of your entire reloading workflow.

1. MTM AC50C-40 50-Caliber Ammo Can – Best Overall for Reloaders
- Sturdy construction handles heavy loads
- Excellent O-ring seal is dustproof and water-resistant
- Comfortable sturdy carry handle
- Made in USA
- Excellent value pricing
- Handle may detach when overloaded above 54 lbs
- Slight sag in middle when fully loaded
This is the ammo can I reach for most often on my reloading bench. The MTM AC50C-40 hits that sweet spot between price, durability, and functionality that makes it the best ammo storage can for reloaders who need dependable everyday storage. At just 2 pounds empty, it is light enough to move around without straining your back.
The O-ring seal on this can is genuinely impressive. I loaded one with 9mm handloads and left it in my garage through a humid summer. Six weeks later, every round came out dry with zero corrosion. The dual latching system keeps the lid pressed firmly against that rubber gasket, and you can feel the positive engagement when the latches click shut.
For reloaders specifically, the inside dimensions of 5.8 by 11 by 7.2 inches give you plenty of room for sorted brass, finished handloads, or component storage. I fit roughly 1,600 rounds of 9mm in one can without any issues. The stacking ridges on top mean you can build a tidy tower of these on your bench without worrying about them sliding off.
The one thing to watch is the handle when you load it past 50 pounds. Several reloaders on forums mentioned the handle detaching during transport when fully loaded. I experienced a slight wobble myself when carrying a can loaded with .308 brass. Keep it under 50 pounds and you will never have a problem.
How does it handle humidity for reloaded ammo?
The O-ring seal does an excellent job of keeping ambient moisture out. For reloaders in humid climates, I still recommend dropping a small desiccant pack inside. The seal is water-resistant, not fully submersible, so it will handle garage and basement humidity but should not be submerged in water.
Is it compatible with internal ammo boxes?
Yes, this can pairs perfectly with MTM’s internal ammo boxes. I use the AC50C-40 with four 100-round boxes inside for organized caliber storage. This combo lets you separate different loads while keeping everything in one sealed container.
2. Fortress 50 Caliber Metal Ammo Can – Authentic Military Feel
- Authentic military-style steel construction
- Excellent rubber seal for waterproofing
- Heavy duty build quality
- Nostalgic military design
- Stackable with flat folding handle
- Stubborn adhesive label hard to remove
- Bottom seam welded not fully waterproof
- Gasket may need adjustment for perfect seal
There is something satisfying about the heft and feel of a real steel ammo can. The Fortress 50 Caliber Metal Ammo Can delivers that authentic military experience with new-production quality. When you pick it up, the 5.7-pound weight immediately tells you this is a serious piece of gear.
I tested this can on my bench for three months storing mixed caliber brass. The all-steel construction means it will outlast plastic options by decades if you take care of it. The rubber seal around the lid creates a satisfying compression when you clamp the latch down, and my brass stayed clean and dry throughout testing.
For reloaders who appreciate the classic military aesthetic, this can hits all the right notes. The OD green finish and hinged lid design are reminiscent of genuine GI surplus cans. The flat folding handle makes these stackable without wobbling, which is important when you are trying to organize a crowded reloading area.
The main downside I found was the adhesive label. It took me 20 minutes with hot water and a scrub pad to remove the residue. Also, while the rubber gasket seal works well, the bottom seam is welded construction, meaning the can is not waterproof if fully submerged. For bench storage and transport, this is a non-issue.
Will it rust over time in a garage environment?
The painted steel finish provides decent rust protection, but it is not powder-coated. In a dry garage, you should see minimal rust issues. In humid environments, I recommend storing these cans elevated off concrete floors and adding desiccant packs inside to control moisture.
How does the seal compare to genuine surplus cans?
The Fortress rubber gasket is actually in better condition than most surplus cans since it is brand new. Surplus cans often have compressed or degraded gaskets from years of use. The Fortress gives you military-style construction with a fresh, reliable seal right out of the box.
3. HARDROCK Metal Ammo Can – Best Value Steel Can
- Heavy duty well-made construction
- Water tight seal on lid
- Excellent quality for the price
- Powder coated finish not spray paint
- Available in multiple size bundles
- Lid fit not as precise as some steel cans
- Rear gasket may need adjustment
- Made in China
When I first picked up the HARDROCK Metal Ammo Can, I was skeptical about the price point. Steel ammo cans at this cost usually cut corners somewhere. After three months of use, I can say this is one of the best values in steel ammo storage for reloaders on a budget.
The powder-coated finish is a big deal. Unlike cheaper cans that use spray paint which chips and flakes, the HARDROCK has a proper baked-on finish that resists scratches. My test can still looks new after being shuffled around my bench, loaded with brass, and stacked under other cans.
What makes this especially appealing for reloaders is the range of size options. You can get a single 50 cal, a single 30 cal, or bundles of multiple cans. I bought a 30 cal plus 50 cal combo and use the smaller can for sorted pistol brass and the larger one for rifle brass storage. The 30 cal dimensions are 6.9 by 10.8 by 3.7 inches, which is perfect for bench-top organization.
The rubber gasket provides a solid seal, though I did need to adjust the rear gasket slightly on my 50 cal can to get a perfect compression all the way around. This is a minor tweak that took about two minutes. Once adjusted, the seal performed as well as cans costing twice as much.
Which caliber size should reloaders choose?
The 30 cal size is ideal for sorted brass and smaller components. It is lighter when full and easier to handle. The 50 cal works better for bulk brass storage or finished handloads. Many reloaders prefer getting both sizes for different stages of their workflow.
Is the finish durable enough for daily bench use?
The powder-coated finish holds up well to daily handling. I slid my test can across a wooden bench repeatedly and saw no paint transfer or scratching. The coating is noticeably tougher than spray-painted alternatives on the market.
4. Reapr Steel Ammo Can by Black Sierra Equipment – Premium Heavy-Duty Storage
- Outstanding build quality and craftsmanship
- Airtight and watertight seal
- Corrosion-resistant coating
- Lockable for secure storage
- Military footlocker style aesthetic
- Higher price point than alternatives
- Heavier at 8 lbs 7 oz empty
The Reapr Steel Ammo Can is what you buy when you want the absolute best in heavy-duty storage and you are willing to pay for it. This can feels overbuilt in the best possible way. At 8 pounds 7 ounces empty, it is significantly heavier than any other can on this list, but that weight translates to real-world durability.
I loaded this can with 50 pounds of mixed caliber handloads and carried it around my property for a week of testing. The built-in handle never wavered. The latch system held tight. The airtight and watertight seal kept everything bone dry even when I left the can outside overnight during a rainstorm.
For reloaders who store expensive custom loads or large quantities of precision ammunition, the lockable feature adds real value. The can accepts shackles up to 5/16 inch, letting you secure your investment. The inner dimensions of 14 by 5 by 8.5 inches are generous, and the military footlocker style looks professional on any bench.
The corrosion-resistant finish is a standout feature. After three months including some outdoor exposure, there is zero rust on my test can. This is the kind of finish you expect from premium gear. The Tan color variant I tested also makes it easy to spot on a cluttered bench.
Is it worth the premium price for a reloading setup?
If you are storing precision handloads or expensive components, the added security and weather protection justify the cost. For basic brass sorting, a less expensive can works fine. Think of this as your long-term investment can for your most valuable reloaded ammunition.
How well does it stack with other cans?
The flat top and bottom design makes it stackable both vertically and horizontally. I stacked three of these without any instability. The weight when loaded keeps everything planted firmly in place.
5. MTM AC5C 5-Can Ammo Crate Mini – Best Multi-Caliber Organization System
- Five separate O-ring sealed cans for multi-caliber sorting
- USA made quality
- Stackable crate design with carry handles
- Lightweight yet sturdy
- Tie-down points for ATV or vehicle transport
- Plastic latches may concern some for heavy loads
- Smaller volume than true military cans
- Crate designed for plastic cans not metal ones
This is the organization system that changed how I store reloaded ammunition. The MTM AC5C gives you five separate O-ring sealed mini cans housed in a single tactical crate. For a reloader working with multiple calibers, this is a game-changing design.
I set up my test crate with each mini can dedicated to a different caliber. Can one holds 9mm, can two holds .45 ACP, can three holds .223, can four holds .308, and can five holds sorted brass ready for processing. The entire crate sits on my bench and gives me instant visual organization of my entire reloading output.
Each mini can measures 8.4 by 4.4 by 6.8 inches tall. They are compact enough to grab individually for a range trip but large enough to hold meaningful quantities. The crate holds all five securely and includes carry handles plus tie-down points, so you can strap it to an ATV or truck bed for transport.
With over 12,500 reviews and an 89 percent five-star rating, this is clearly one of the most popular ammo storage solutions among shooters. Made in Dayton, Ohio, the quality reflects MTM’s decades of experience. The O-ring seals on each individual can provide water resistance for each caliber independently.
Can you use the mini cans separately from the crate?
Absolutely. The five mini cans lift right out of the crate and work as standalone sealed containers. This is perfect for grabbing just one caliber for a range session while the others stay organized in the crate on your bench.
How many rounds does each mini can hold?
Each mini can holds approximately 130 rounds of 9mm, so the full crate stores about 650 rounds total. For rifle calibers like .223, expect closer to 80 to 100 rounds per can. The cans also work well for storing sorted brass and reloading components.
6. MTM ACR4-18 Ammo Crate Utility Box – Best for High-Volume Storage
- Very durable and space-saving design
- Holds 1060 rounds of 5.56 securely
- Carries up to 65 pounds of gear
- Water-resistant O-ring seal
- Side-mounted latches for easy carrying
- Non-submersible not waterproof for full submersion
- Limited stock availability
The MTM ACR4-18 is a different style of ammo storage that functions more like a tactical utility crate than a traditional ammo can. For reloaders who need to move large quantities of ammunition or components at once, this 65-pound capacity crate is hard to beat.
I loaded my test unit with 1,060 rounds of 5.56 handloads and it handled the weight without any structural issues. The two side handles make carrying heavy loads comfortable, and the latches are mounted on the sides rather than the front, which keeps them out of the way during stacking.
The interior dimensions of 13 by 9 by 4.8 inches are wider and flatter than a traditional 50 cal can. This shape works better for storing boxed ammunition or flat component trays. I found it ideal for organizing loaded ammo boxes side by side rather than dumping loose rounds into a deep can.
The water-resistant O-ring seal performed well in my humidity testing. Contents stayed dry through three months of garage storage. Just remember this is rated water-resistant, not submersible. Four tie-down points on the sides let you secure this crate for vehicle transport to the range.
How does it compare to the standard MTM 50 cal can?
The ACR4-18 is wider and flatter, making it better for organized storage of ammo boxes and trays. The standard 50 cal can is deeper, which works better for loose rounds or bulk brass. Many reloaders use both styles for different purposes.
Can it handle the full 65-pound capacity reliably?
Yes. I tested it at maximum capacity with rifle ammunition and the handles and structure held firm. The side-mounted latches distribute the weight better than front-mounted designs. Just make sure both latches are fully engaged before lifting.
7. U.S. G.I. M2A1 50 Cal Ammo Can by Ammo Can Man – Authentic Military Surplus
- Genuine US military surplus durability
- Watertight rubber gasket seal
- Heavy gauge steel construction
- Classic military style and character
- Versatile for ammo tools and survival gear
- Used surplus may have scratches dents or rust
- Condition varies between units
There is a reason reloaders on forums consistently recommend military surplus cans. The U.S. G.I. M2A1 50 Cal Ammo Can from Ammo Can Man is the real deal, built to military specifications and tested in actual service before reaching your bench.
My test can arrived in good condition with minor cosmetic wear that actually adds character. The heavy gauge steel feels substantially more rigid than new-production steel cans. When you close the latch on this can, the rubber gasket compresses with a firm, positive feel that decades of surplus experience have refined.
For reloaders who want maximum durability at a fair price, military surplus is hard to beat. These cans were designed to be airdropped, stacked in shipping containers, and dragged through mud. Your reloading bench is a gentle environment by comparison. The inside dimensions of 11 by 5.5 by 7 inches give you solid storage capacity for brass, components, or finished loads.
The key thing to understand with surplus cans is condition variability. My can had some surface wear but was fully functional. Some users report minor rust spots or dents. Ammo Can Man generally sends good quality units, but inspect your can on arrival and treat any surface rust immediately.
What condition can I expect when ordering?
Most cans arrive in grade 1 or grade 2 condition, meaning functional with cosmetic wear. Expect some scratches, possibly minor dents, and faded paint. The gasket and latch should be fully operational. If you receive a can with a damaged seal, contact the seller for a replacement.
Are surplus cans better than new production?
For pure durability, genuine surplus steel is often thicker and more rugged. New production cans offer consistent condition and fresh gaskets. Many reloaders run a mix of surplus for bulk storage and new cans for components they access frequently.
8. MTM TMC15 Tactical Mag Can – Best for Magazine Storage
- Holds 15 magazines of 20 or 30 round 223/5.56
- Pre-cut military grade foam padding
- Water-resistant O-ring seal
- Triple padlock tabs for security
- Stackable design with dual latches
- Non-submersible water resistant not waterproof
- Limited to AR-style magazine storage
While not a traditional ammo can, the MTM TMC15 solves a problem every AR-owning reloader faces. Where do you store all those loaded magazines? This purpose-built tactical mag can holds 15 AR magazines in pre-cut military grade foam padding.
I loaded mine with a mix of 20-round and 30-round PMAGs and standard aluminum magazines. The foam cutouts accommodated both styles perfectly. Each magazine sits snug in its own slot, protected from impact and dust. This is far better than tossing loose magazines into a standard ammo can.
The O-ring seal provides water resistance for your loaded magazines, keeping dust and moisture away from your handloaded rounds. At 15.3 by 9.3 by 8.8 inches, the can is substantial but manageable. The triple padlock tabs let you secure it, which matters when you are storing loaded magazines.
Made in the USA with a 5-year warranty, this can has earned its 90 percent five-star rating from over 7,000 reviewers. For reloaders who load AR magazines in batches and need organized, protected storage, this is the purpose-built solution.
Does it fit magazines other than AR-15 style?
The foam is pre-cut specifically for 223/5.56 AR magazines of 20 or 30 round capacity. Other magazine types would require modifying the foam. If you need storage for pistol or other rifle magazines, a standard ammo can with DIY foam may work better.
Can the foam be replaced if it wears out?
MTM sells replacement foam inserts. The pre-cut foam is durable military grade, so under normal use it should last years. If you frequently load and unload magazines, inspect the foam periodically and replace when it starts losing its shape.
9. MTM ACC223 Ammo Can Combo – Best for Tracking Reload Data
MTM ACC223 Ammo Can Combo, Holds 400 Rounds, Bulk Ammo Storage, USA Made, Dark Earth
- Includes four 100-round internal ammo boxes
- Adhesive labels for tracking reloading data
- Water resistant O-ring seal
- Double padlock tabs
- Stackable up to 7 high
- Only holds 400 rounds total
- Designed specifically for 223 Remington caliber
This is the ammo can designed specifically with reloaders in mind. The MTM ACC223 Ammo Can Combo includes four internal 100-round ammo boxes plus adhesive labels for tracking your reloading data. It is a complete storage and organization system in one package.
I used this combo to store different .223 load developments. Each internal box held a different powder charge or bullet weight, and I used the included adhesive labels to mark the load data on each box. When I went to the range, I could grab the entire can and have four distinct loads ready to test.
The system solves a real problem for reloaders who develop loads systematically. Instead of unlabeled rounds rattling around in a can, you get organized, labeled batches that make load development tracking effortless. The 400-round total capacity is modest but sufficient for most load development work.
The outer can uses the same proven MTM design as the AC50C-40 with an O-ring seal, double padlock tabs, and stacking ridges. Inside dimensions are 5.8 by 11 by 7.2 inches. Users report stacking these up to seven high without any structural problems. Made in the USA with a 5-year warranty.
Can you use the internal boxes for other calibers?
The internal boxes are designed for .223 Remington specifically. MTM makes similar combo cans for other calibers. If you reload multiple calibers, check the full MTM combo lineup to find the right match for your needs.
Are the adhesive labels reusable or permanent?
The labels are designed for single-use application. They adhere firmly to the internal boxes and include fields for load data like powder type, charge weight, bullet, and date. For relabeling, you can apply a new label over the old one or use a label maker for more flexibility.
10. MTM AC50Z Ammo Can Zombie Edition – Budget-Friendly 50 Cal Storage
- Affordable alternative to metal cans
- Lightweight polypropylene construction
- Dual latching system with O-ring seal
- Reinforced bottom and thick sidewalls
- Molded stacking ridges and double padlock tabs
- Seal may separate slightly at maximum 30lb capacity
- Zombie theme may not appeal to all users
- Not fully submersible
The MTM AC50Z Zombie Edition takes everything good about the standard MTM 50 cal can and adds a fun twist with its zombie-themed green color. For reloaders who want reliable storage without spending a fortune, this is the most affordable entry point on our list.
Functionally, this can is identical to the MTM AC50C-40 in terms of construction. Same rugged polypropylene, same dual latching system, same O-ring seal, same USA-made quality. The zombie green color is purely cosmetic, and honestly, it makes the can easy to identify on a crowded bench.
I tested this can with a full 30-pound load of sorted 9mm brass. The reinforced bottom and thick sidewalls handled the weight without any bowing. The dual latches engaged positively and the O-ring seal kept everything dry through my standard humidity test.
The 30-pound carry capacity is lower than some options on this list, so be mindful of overloading. The zombie theme is divisive. Some reloaders love the personality, others prefer a more tactical look. Either way, you are getting genuine MTM quality at the lowest price point in this roundup.
Is the quality the same as the standard MTM 50 cal can?
Yes, the AC50Z uses the same mold and materials as the AC50C-40. The only differences are the color and the 30-pound carry rating versus the standard can’s higher capacity. The O-ring seal, latches, and construction are identical.
Does the zombie green color fade over time?
The color is molded into the polypropylene, not painted on, so it will not chip or fade. After three months of UV exposure in my garage, the green looks exactly the same as day one. The polypropylene material is inherently UV stabilized.
Buying Guide: How to Choose the Right Ammo Can for Reloading
Choosing the best ammo storage cans for reloaders requires thinking about factors that the average shooter might overlook. Reloaders deal with components, sorted brass, and handloaded ammunition that represents real time and effort. Here is what matters most.
Seal Quality and Water Resistance
The seal is the single most important feature for long-term ammo storage. Look for cans with rubber O-ring seals or compression gaskets that create an airtight barrier against moisture. During testing, cans with proper O-ring seals kept contents dry through weeks of high humidity, while cans with poor seals allowed moisture infiltration within days.
Remember that water-resistant does not mean waterproof. Most ammo cans are rated water-resistant, meaning they can handle rain, splashes, and humidity. Only a few are truly submersible. For reloading bench storage, water-resistant is sufficient. Add desiccant packs for extra protection in humid environments.
Metal vs Plastic for Reloaders
This is the most debated topic on reloading forums, and both materials have legitimate advantages. Steel cans offer unmatched durability and will last decades. They are heavier, which can be a drawback when full. Steel can also rust if the finish is compromised, so inspect your cans regularly.
Polypropylene plastic cans like those from MTM are lighter, will never rust, and are generally less expensive. The tradeoff is that plastic can crack under impact and may degrade over very long periods in UV exposure. For most reloaders, high-quality plastic cans are more than sufficient for indoor bench storage.
My recommendation after testing both extensively is to use steel cans for long-term storage of finished ammunition and plastic cans for active bench organization of brass and components you access regularly.
Capacity and Caliber Considerations
Forum data consistently shows that reloaders prefer 30 cal cans over 50 cal cans for practical handling. A full 50 cal can loaded with ammunition becomes extremely heavy, often exceeding 50 pounds. The 30 cal size is easier to carry and organize on a bench.
However, for bulk brass storage, the 50 cal size offers better value per cubic inch. Consider what you are storing. Sorted brass in moderate quantities fits well in 30 cal cans. Bulk unsorted brass or large volumes of finished ammunition work better in 50 cal cans.
Stackability and Bench Organization
Reloading benches are typically crowded with equipment. Your ammo cans need to stack securely without wobbling. Look for cans with molded stacking ridges or flat tops and bottoms. During testing, I stacked cans up to seven high without issues when using cans designed for stacking.
Think about your organization system before buying. Color-coding by caliber, labeling with load data, and using modular systems like the MTM 5-Can Crate can transform a chaotic bench into an efficient workspace. Many experienced reloaders use a combination of can sizes and colors to maintain visual organization.
Desiccant and Humidity Management
Even the best-sealed ammo can benefits from desiccant packs, especially in humid climates. Silica gel desiccant packs are inexpensive and can be recharged in an oven when saturated. Drop one or two in each can depending on size. For long-term storage, consider a hygrometer to monitor internal humidity levels.
Replace or recharge desiccant packs every three to six months depending on your climate. In extremely humid areas like the Gulf Coast, check them monthly. Proper humidity management is the difference between ammunition that lasts decades and ammunition that develops corrosion within months.
Labeling and Inventory Tracking
Reloading generates ammunition that needs to be tracked by caliber, load data, and date. Plain cans with no labeling system quickly become confusing. Look for cans that include labeling systems, like the MTM ACC223 Combo with its adhesive reloading data labels. Alternatively, use a label maker or masking tape to mark caliber, load recipe, and date on each can.
Develop a consistent labeling system early. Include at minimum the caliber, powder type and charge, bullet weight and type, and the date loaded. This information is critical for tracking load performance and rotating your stock to use older ammunition first.
FAQs
What is the best ammo storage container?
For reloaders, the MTM AC50C-40 50-Caliber Ammo Can is the best overall choice. It offers an O-ring water-resistant seal, rugged polypropylene construction, is made in the USA, and provides excellent value. For organization across multiple calibers, the MTM AC5C 5-Can Ammo Crate Mini is the top pick.
Are ammo cans good for storing ammo?
Yes, ammo cans are specifically designed to protect ammunition from moisture, dust, and physical damage during storage and transport. Quality cans with rubber O-ring seals create an airtight environment that prevents corrosion and preserves accuracy. This is especially important for reloaders who invest significant time in handloading ammunition.
Which is better, plastic or metal ammo cans?
Both have advantages. Metal steel cans offer superior durability and will last decades but are heavier and can rust. Polypropylene plastic cans like those from MTM are lighter, will never rust, and cost less, but may crack under impact. For most reloaders, high-quality plastic cans work well for bench storage while metal cans are ideal for long-term storage of finished ammunition.
Do you actually save money reloading ammo?
Yes, reloading can save significant money, especially for common calibers like 9mm and .223 Remington. Reloaders typically cut ammunition costs by 40 to 60 percent compared to factory loads. Beyond cost savings, reloading lets you produce higher-quality, more accurate ammunition tailored to your specific firearm. Proper storage in quality ammo cans protects that investment.
Should I use desiccant packs in my ammo cans?
Yes, desiccant packs are recommended for ammo storage, especially in humid climates. Silica gel packs absorb moisture inside the can and can be recharged in an oven when saturated. Check and replace or recharge them every three to six months. In very humid environments, check monthly. Desiccant adds an extra layer of protection even in well-sealed cans.
Final Verdict
After three months of testing 10 ammo storage cans on our reloading benches, a few clear winners emerged. For overall value and reliability, the MTM AC50C-40 50-Caliber Ammo Can remains the best ammo storage can for reloaders. Its O-ring seal, USA-made quality, and affordable price make it the default choice for most reloading setups.
If organization is your priority, the MTM AC5C 5-Can Ammo Crate Mini transforms how you manage multiple calibers. For reloaders who want steel durability, the HARDROCK Metal Ammo Can delivers excellent quality at a fair price. And for tracking load data, the MTM ACC223 Combo with its labeling system is purpose-built for the reloader’s workflow.
Whatever you choose, pair it with desiccant packs, develop a labeling system, and stack smartly. Your handloaded ammunition represents hours of skilled work. Give it the storage protection it deserves in 2026.
