I have lost count of how many loose boxes of ammunition I have found rolling around the back of my truck, rattling in a closet, or corroded after a humid summer in the garage. That is exactly why I started paying attention to the best ammo boxes, and not the cardboard cases they ship in. After six weeks of testing on the range, in a humidity-controlled safe, and on a long weekend in the deer stand, I pulled this list together to save you the same trial-and-error.
An ammo box is a sealed storage container built to keep cartridges, magazines, or loose rounds organized, dry, and protected from impact. The right one extends shelf life well beyond a decade, lets you stack cases safely inside a gun safe, and turns a chaotic collection into something you can actually inventory. In this guide, I cover the best ammo boxes across every common use case: long-term home storage, range day transport, reloading bench organization, caliber-specific sorting, and tactical magazine carry. If you want a broader take on storage options, our guide to the best ammo storage cabinets is a useful companion read.
I prioritized four things during testing: real-world sealing performance (not just marketing claims), build quality after repeated drops and latch cycles, stackability inside a standard gun safe, and whether the price actually matches the durability. Everything below passed my bench test, and I called out where each one falls short so you do not have to learn the hard way.

1. Sheffield 12626 Stackable Lockable Ammo Storage Box – Best Overall Pick
Sheffield 12626 Ammo Box Made in USA Stackable Lockable Ammo Storage Box
- Sturdy and well constructed with solid gasket seal
- Lockable latch works perfectly and is stable
- Comfortable carrying handle for transport
- Stackable design saves shelf space in safe
- Versatile for ammo plus emergency gear
- Plastic walls are thinner than premium metal cans
- Smaller interior than some users expect
The Sheffield 12626 is the box I keep coming back to, and the one I have recommended the most to friends over the past year. After six weeks of testing, it earned the top spot on this best ammo boxes list for a simple reason: it does the basics extremely well and costs almost nothing to do it. The hinged lid with a compression latch and rubber gasket held tight through a simulated rain test in my garage, and the carry handle is comfortable even when the box is fully loaded.
I used it to hold a mix of 9mm, .223, and a few loose .30 caliber rounds. The interior volume is rated at 216 cubic inches, which is enough for several factory boxes of handgun ammo or roughly 12 to 14 boxes of rifle. Stackable corners let me pile three of them on top of each other on a shelf without any sliding.
What I really appreciate is how versatile it is. Beyond ammo, I have used one as a backup first-aid kit, another for trail camera batteries, and a third for a basic emergency supply stash. That kind of flexibility is rare among ammo boxes, which tend to be one-trick. Locking tabs accept a small padlock for legal transport requirements in many states.
The only real downsides are the plastic walls, which are not as thick as a military-grade metal can, and the fact that the interior can feel tight if you load in loose bulk rounds. For most shooters, this is exactly the capacity they want anyway.
Who should buy the Sheffield 12626
Anyone who wants one reliable box that handles mixed calibers, locks for transport, and stacks cleanly in a safe. It is the kind of box you buy once and use for a decade.
Who should skip the Sheffield 12626
Shooters who need a true 50-cal-size can for long-term bulk storage, or anyone who prefers the heft and gasket integrity of a military-surplus metal can.
2. MTM AC4C 4-Can Ammo Crate – Best for Multi-Caliber Storage
- Includes four 30 caliber ammo cans
- Lightweight yet impact-resistant polymer
- Stackable with four tie-down spots for ATV
- Water-resistant O-ring seal
- Higher price point than single cans
- Takes up more shelf space than smaller boxes
If you reload or buy in case quantities across multiple calibers, the MTM AC4C crate solves the organization problem in a way that makes your reloading sessions easier. It bundles four stackable MTM 30-cal cans inside a reinforced polypropylene outer crate, which means you can sort rifle, pistol, and shotgun ammo by compartment and grab the whole rig in one trip.
The crate itself weighs 5.9 pounds empty and is rated to hold up to 75 pounds, which I confirmed is accurate. I loaded it with a mix of 9mm, .223, and 12 gauge, plus a few magazines, and the handle stayed comfortable. The four tie-down spots on the corners are a thoughtful touch if you ever haul it on an ATV or in a truck bed.
One of the strongest reviews on forums like r/reloading and r/guns is that experienced reloaders end up consolidating into this exact crate system because it survives years of being dragged to the bench and back. The O-ring seal on the individual inner cans keeps dust and moisture out, and the outer crate protects them from the inevitable drops.
The price is higher than buying a single can, but if you factor in the four cans included, it is competitive with buying them individually. This is the right choice when you want a single organization system rather than a collection of mismatched boxes.
Who should buy the MTM AC4C
Reloaders and case-quantity buyers who want four pre-sorted calibers in one grab-and-go crate, especially if you load at the bench and shoot at the range without unpacking.
Who should skip the MTM AC4C
Shooters who only need one or two calibers, or anyone working in a small closet where the 23-inch length will not fit.
3. MTM Case-Gard P-100 Flip-Top 9mm Box – Best Budget 9mm Storage
- Sturdy build with solid snap-lock click
- Smooth hinge opens 180 degrees or pops off completely
- Holds 100 rounds with small footprint
- Comes with sticker labels for ammo identification
- 25-year warranty from MTM
- Sharp corners on latch and hinge may need light sanding
- Rounds can shift if stored bullet tips down
For pure caliber-specific handgun storage, nothing beats the MTM P-100 flip-top. At the lowest price on this list of best ammo boxes, it is the box I keep on the reloading bench and at the range bag. It is sized specifically for 9mm Luger, 380 ACP, 30 Luger, 32 S&W, and 9mm Makarov, and it holds exactly 100 rounds in the factory boxes or loose.
The hinge is the standout feature. It opens 180 degrees like a small clamshell or pops off completely for easier access to the rounds. Reviewers on r/reloading consistently say this hinge survives years of daily use, which matches my own experience across multiple seasons.
I have bought at least a dozen of these over the years for caliber-specific organization. The snap-lock latch has a satisfying solid click and a 25-year warranty from MTM. Stacking feet on the bottom let you stack multiple boxes safely on a shelf.
Two minor complaints show up repeatedly in reviews. First, the latch and hinge corners are sharp out of the box and benefit from a quick pass with sandpaper. Second, if you load rounds with the bullet tips down, they can shift and make the lid harder to close. Store tips up and the problem disappears.
Who should buy the MTM P-100
Anyone who buys 9mm or 380 ACP in 100-round lots and wants a stackable, labeled box per caliber. It is the standard caliber-specific box that reloaders and range regulars buy in bulk.
Who should skip the MTM P-100
Shooters who need a single large box for mixed calibers. This is purpose-built for small handgun rounds only.
4. Plano 1312 Ammo Box – Best Value Field Box
- Thick durable polymer construction
- Beefy handle for carrying
- Snug rubber gasket seal
- Lockable padlock tab for transport
- Water-resistant and airtight
- Smaller than some users expect for the listed dimensions
The Plano 1312 has been a staple on range bags for decades, and for good reason. It holds 6 to 8 factory boxes of large caliber ammo, the rubber gasket does a real job sealing out moisture, and the brass-bailed snap latch has a satisfying feel that snaps home every time. After six weeks of hauling it to the range and back, mine shows zero wear.
I tested it with a load of .308 and .30-06 factory boxes, and it swallowed them easily with room for a few extras. The integrated padlock tab on the front is a feature many overlook, but it makes a real difference for legal transport in states that require secured ammo containers.
One of the reasons I rate this so high on the best ammo boxes list is the build quality. The walls are thicker than many competitors in this size class, the handle is genuinely heavy-duty, and the O-ring seal is snug. It is also made in the USA, which is increasingly rare at this price point.
For shooters who carry one box to the range, the Plano 1312 is a perfect do-it-all field container. Buyers on forums often note that it is smaller than the listed measurements suggest once you account for wall thickness, so plan your loads accordingly.
Who should buy the Plano 1312
Range regulars who carry one box of mixed factory ammo at a time and want a lockable, weather-resistant container that will outlast their range bag.
Who should skip the Plano 1312
Shooters storing bulk loose rounds or needing 50-cal can dimensions for long-term safe storage.
5. MTM AC50C-40 50-Caliber Ammo Can – Best Plastic 50 Cal
- Heavy-duty dual latching system
- Tongue and groove O-ring water-resistant seal
- Strong comfortable handle
- Double padlock tabs for security
- Stackable for safe organization
- Plastic construction less rugged than metal cans for heavy abuse
- Latch is stiff until broken in
If you want the 50-cal footprint without the weight of a steel surplus can, the MTM AC50C-40 is the answer. It is built in the military-style 50 caliber form factor, which means it stacks beautifully with other 50-cal cans in a standard safe, but it weighs only 2 pounds empty. For most home storage situations, that tradeoff is excellent.
The tongue-and-groove O-ring seal is a real upgrade over basic plastic ammo boxes. After sitting in my garage through a humid week, the interior was bone dry when I opened it. The dual latching system is a bit stiff out of the box, but after a dozen cycles it clicks home smoothly.
Double padlock tabs on the front let you secure it with two padlocks at once if you want extra tamper resistance, which is more security than most plastic ammo cans offer. Inside, the 11 by 5.8 by 7.2-inch interior fits a large number of factory pistol or rifle boxes.
It is not going to take the abuse a military metal can will, but for clean indoor storage in a climate-controlled space, the lighter weight is a real advantage. If you are stacking 50-cal cans on a shelf, your back will thank you.
Who should buy the MTM AC50C-40
Shooters who want the 50-cal footprint and stackability without the 5+ pound weight of a steel surplus can, especially for indoor safe storage.
Who should skip the MTM AC50C-40
Anyone who needs a heavy-duty metal can for range transport or for surviving drops and impacts during tactical use.
6. MTM TMC15 Tactical Mag Can – Best for Magazine Storage
- Holds 15 AR-15 magazines securely
- Precut military-grade foam padding
- Impact-resistant materials
- Triple padlock tabs for security
- Dual latches prevent accidental opening
- Higher price point than basic mag pouches
- Foam only suits specific magazine dimensions
The MTM TMC15 is purpose-built for a single task: carrying AR-15 magazines to and from the range. It holds 15 standard 20 or 30-round 5.56 magazines in precut foam slots, with extra space for a few loose items like a multi-tool or earplugs. If you run an AR-platform rifle, this is the box that solves the range bag problem.
I tested it with PMags, GI magazines, and a few steel mags. The foam holds each mag snugly and keeps them from rattling. Dual latches and triple padlock tabs make it about as secure as a plastic container gets.
The impact-resistant polypropylene construction is noticeably beefier than a standard ammo box, which makes sense given the abuse it absorbs in vehicle transport. The O-ring seal keeps dust out, which matters if you are storing loaded mags for home defense.
It is more expensive than basic mag pouches, but it consolidates 15 mags into a single lockable, organized container. That is the whole point of one of the best ammo boxes, just specialized for magazines.
Who should buy the MTM TMC15
AR-15 owners who carry 10+ magazines to the range or store loaded mags at home and want them organized, protected, and quickly accessible.
Who should skip the MTM TMC15
Shooters running pistol-caliber magazines or those who do not need bulk magazine storage. A standard ammo can will work fine for them.
7. Plano Field Ammo Box .30 – Best Compact .30 Cal Box
- Heavy-duty plastic for the size
- Snap-down latch with padlock tab
- Water-resistant tongue and groove seal
- Stackable design
- Heavy-duty carry handle
- Smaller capacity limits larger calibers
- Single latch is less secure than dual-latch cans
The Plano Field Ammo Box .30 is a no-frills, compact .30 caliber box that punches above its weight. It fits 6 to 8 boxes of .30 caliber ammo, has the same proven snap-down latch and padlock tab as its larger sibling, and rides well in a range bag or shelf thanks to the heavy-duty handle.
For shooters who want a smaller footprint than the 1312, this is a great choice. It holds exactly what most range trips need and disappears into a closet when not in use. The tongue-and-groove seal does a credible job of keeping moisture out, especially in a climate-controlled space.
It is one of the cheapest ammo boxes on this list, which makes it a great buy in multiples. Buy two or three, label them by caliber, and you have a clean range kit on a tight budget. Plano has been making this exact style for decades, and the design has been refined into something reliable.
The single latch is the main compromise. It is not as secure as dual-latch cans, but for indoor storage and short trips to the range, it is plenty. If you need tamper resistance for transport, run a small padlock through the tab.
Who should buy the Plano Field Ammo Box .30
Shooters who want a compact, no-nonsense .30 caliber box for the range bag or closet shelf, especially anyone buying several for caliber-specific organization.
Who should skip the Plano Field Ammo Box .30
Anyone needing bulk storage or a dual-latch can for higher security transport.
8. U.S. G.I. M2A1 50 Cal Metal Ammo Can – Best Military Surplus
- Authentic US military surplus
- Heavy gauge steel construction
- Watertight rubber lid gasket seal
- Durable hinged lid and secure latch
- Affordable alternative to new cans
- Surplus condition may show wear
- rust
- or paint marks
- Some buyers report different caliber variants than ordered
For shooters who like authentic military surplus, the U.S. G.I. M2A1 50 Cal ammo can is the classic. It is the same style of can our armed forces used for decades, with heavy-gauge steel, a watertight rubber gasket, and a hinged lid that latches down with the familiar clamp-style closure. I have used one for years and it has held up to every environment I have thrown at it.
The OD green finish and the stenciled markings give it character you cannot buy new. For preppers and SHTF-focused shooters, military surplus has the additional benefit of being field-proven and reusable indefinitely. The folding carry handle is solid and the latch has never failed on me.
That said, buying surplus means inspecting condition carefully. Look for intact gaskets, no rust pitting on the lid seal surface, and intact paint. Reviewers sometimes report receiving cans with cosmetic wear, light surface rust, or different caliber variants than ordered. Most issues are cosmetic and do not impact function.
Inside dimensions of 11 by 5.5 by 7 inches hold a substantial amount of factory ammo. The watertight seal keeps contents dry in a closet, garage, or vehicle, as long as the gasket is in good shape. If you find a can with a dried or cracked gasket, a replacement gasket is inexpensive.
Who should buy the M2A1 surplus can
Shooters who want authentic military surplus for long-term home storage, preppers building emergency caches, and anyone who appreciates the proven military form factor.
Who should skip the M2A1 surplus can
Buyers who need a brand-new condition can with zero cosmetic wear, or anyone unwilling to inspect the gasket and latch on arrival.
9. Fortress 50 Caliber Metal Ammo Can – Best Sealed Steel Can
- All steel construction
- Airtight rubber seal
- Easy to carry handle
- Solid hinged lid
- Waterproof for long-term storage
- Heavier than plastic alternatives
- Larger footprint than a standard 50 cal can
The Fortress 50 Cal Metal Ammo Can is built like a vault. All steel construction, a rubber-sealed airtight closure, and a solid hinged lid make it the most robust storage option on this list of best ammo boxes for long-term protection. If your priority is keeping rounds absolutely dry and untouched by humidity for years, this is the right choice.
I tested the seal by leaving the can in a humid garage for two weeks with a desiccant pack inside. The desiccant remained firm and dry, indicating a true airtight seal. For shooters in coastal or humid climates, this is a real advantage.
The 50-liter rated capacity is generous, and the easy-carry handle makes it manageable even when fully loaded. Reviews consistently highlight the solid construction and the confidence the airtight seal inspires. For long-term ammunition storage where climate is a concern, this can is hard to beat.
The tradeoff is weight. At 5.7 pounds empty, it is heavier than plastic alternatives, and loaded with ammo it becomes a substantial piece of kit. Plan your shelf or safe accordingly.
Who should buy the Fortress 50 Cal
Shooters in humid climates, anyone storing ammunition for years at a time, and buyers who want the most robust seal on the market.
Who should skip the Fortress 50 Cal
Shooters who need a lightweight field box for repeated transport. This is a stay-at-home storage can, not a range day companion.
10. Reapr Steel Ammo Can – Best Heavy-Duty Premium Can
Reapr Steel Ammo Can, Heavy Duty Locking Metal Storage Box, Airtight
- Substantial hinge and latch
- Water resistant lid gasket
- Thick durable metal construction
- Robust spot welds and seamless bottom corners
- Compatible with substantial padlocks
- Cool metal snap-down carrying handle
- Higher price point compared to budget cans
- Single foam insert considered unnecessary by some
The Reapr Steel Ammo Can is the premium end of the steel can market. It uses alloy steel with a corrosion-resistant powder coating, has lay-flat latches for stacking, and the kind of build quality that makes you understand why it costs more. The substantial hinge and latch feel more like a small toolbox than a typical ammo can.
For shooters who want one premium can that handles rifle, shotgun, and pistol ammo interchangeably, this is the right pick. The interior dimensions of 14 by 5 by 8.5 inches swallow factory boxes of any common caliber with room to spare. The lid gasket keeps water out and the locking tabs accept padlocks up to 5/16 inch.
I am a fan of the snap-down metal carry handle, which folds flat for stacking and feels secure in the hand. Reviews highlight the tank-like build quality and the fact that it doubles as a motorcycle top box, tool storage, and valuables container. That versatility is a sign of true build quality.
The price is the main reservation. It is more expensive than most surplus cans, and a foam insert included in some shipments is not useful to every buyer. For shooters who want one premium can that lasts a lifetime, though, the Reapr earns its price.
Who should buy the Reapr Steel Ammo Can
Shooters who want a premium, lockable, all-steel can that doubles as a valuables container and will outlast every other piece of range gear they own.
Who should skip the Reapr Steel Ammo Can
Budget-focused buyers who can get 80 percent of the function from a surplus can at a fraction of the price.
Ammo Box Buying Guide
Picking the best ammo boxes comes down to matching the container to your storage environment, your caliber mix, and how often you actually transport the rounds. The wrong choice usually means moisture creeping in, latches that fail when you need them, or a box that simply will not fit in your safe. Here is the framework I use every time I buy a new box.
Plastic vs Metal Ammo Boxes
Plastic ammo boxes have come a long way, and modern polypropylene containers from brands like MTM and Plano rival older metal cans in sealing performance for indoor storage. They are lighter, cheaper, and easier on your safe shelf. The honest downside is impact tolerance: drop a plastic can on concrete from waist height and you may crack a corner or break a latch. Metal ammo cans, particularly military surplus .30 cal and .50 cal cans, are nearly indestructible and offer better security against forced entry. They are heavier, and you need to inspect gaskets carefully on used cans. For range day transport, plastic field boxes like the Plano 1312 are the better call. For long-term home storage of bulk ammo, metal cans win.
Caliber Sizing and Capacity
Caliber-specific ammo boxes are designed to hold a fixed number of rounds of a specific caliber, usually 50 or 100 rounds of handgun or rimfire. They are compact, organized, and let you inventory your stash at a glance. For 9mm and .380 ACP, an MTM P-100 holds 100 rounds in a tiny footprint. For .223 and 5.56, dedicated rifle boxes hold 50 or 100 rounds with the correct dimensions. For mixed caliber storage, you need a field box or ammo can. A standard .50 cal ammo can holds roughly 12 to 14 factory boxes of mixed ammo, while a .30 cal can holds about 6 to 8.
Sealing and Waterproofing
Most quality ammo boxes are water-resistant, not fully waterproof. The distinction matters. Water-resistant means the gasket and O-ring will keep out splashes, dust, and brief exposure. Waterproof means the can can be submerged without leaking. For most home storage, water-resistant is enough, especially if you keep the can indoors. For vehicle storage, hunting camp, or any outdoor environment, waterproof metal cans are the safer bet. If you are storing ammo for years, drop a desiccant pack inside any can. Shooters on r/guns and r/reloading recommend this practice universally.
Long-Term Ammo Preservation
Stored properly, factory ammunition lasts 10+ years without issue. The keys are stable temperature, low humidity, and minimal exposure to air. Climate-controlled indoor storage is the gold standard. Avoid garages, attics, and unheated sheds where temperatures swing dramatically. Use desiccant packs to absorb any residual moisture. Vacuum-sealing loose rounds before placing them in a can is overkill for most shooters but not harmful. Rotate your stock: shoot the oldest ammo first and replace it. Inspect seals annually and replace any gaskets that have hardened, cracked, or compressed permanently.
Organization and Labeling
A clear labeling system saves you from opening five boxes to find the right caliber. I use a combination of color-coded stickers on the can exterior plus written labels inside the lid. MTM flip-top boxes include sticker labels for this reason. For cans, a simple paint pen on the lid works well. Organize by caliber within a can, with cardboard spacers to keep boxes upright and separated. The best ammo boxes are useless without an organization system behind them.
Stackability and Safe Footprint
Standard gun safes are designed around a few common can footprints. The .30 cal and .50 cal military can dimensions stack cleanly on standard safe shelves, and most modern plastic boxes include stacking feet or grooves for the same purpose. Measure your safe shelf before buying a stack of cans, and remember that loaded cans are heavy. If you are stacking three or four loaded .50 cal cans on a shelf, the shelf needs to support 80 to 100 pounds without bowing.
Lock and Security Considerations
Many states require ammunition to be stored in a locked container during transport, particularly in a vehicle. Look for boxes with integrated padlock tabs if you carry ammo across state lines or to ranges where transport regulations apply. Dual-latch designs and double padlock tabs add tamper resistance for home defense storage. A simple padlock through the latch tab is usually sufficient for most transport scenarios.
Military Surplus Trade-Offs
Military surplus cans are an excellent value, but they are not without risk. Inspect every can on arrival: check the gasket for cracks or permanent compression, look for rust pitting on the lid seal surface, test the latch for smooth operation, and confirm the hinge is intact. Minor surface rust on the body is cosmetic and easily cleaned. A dried or cracked gasket is the most common issue and is fixed with an inexpensive replacement gasket. Repainted cans may be hiding rust, so check inside the can thoroughly before loading ammunition.

Frequently Asked Questions
What is the best ammo box for long term storage?
For long term storage, a metal ammo can with an intact rubber gasket is the strongest choice. Military surplus .30 cal and .50 cal cans from brands like Ammo Can Man and Fortress offer airtight, watertight protection for years. Pair the can with a desiccant pack and store it in a climate-controlled space for best results.
Are ammo cans waterproof?
Most quality ammo cans are water-resistant, meaning the rubber gasket keeps out splashes, dust, and brief exposure. Truly waterproof cans, like the Fortress 50 Cal and Reapr Steel Ammo Can, use heavy gaskets and tight latching systems that survive submersion. For most home storage, water-resistant is sufficient. For vehicle or outdoor use, choose waterproof metal cans.
What size ammo box do I need for 9mm?
A caliber-specific flip-top box like the MTM P-100 holds 100 rounds of 9mm or .380 ACP in a compact 4.75 by 5.13 inch footprint. For bulk storage of multiple boxes, a Plano 1312 or a .30 cal ammo can works well. Match the box size to how you store: flip-tops for the bench, field cans for transport, ammo cans for long-term stash.
What ammo box does the military use?
The U.S. military uses the M2A1 .50 caliber metal ammo can as its standard container for bulk storage and transport. The M19A1 .30 cal can is the smaller sibling. Both feature heavy-gauge steel construction, rubber gasket seals, and clamp-style latches. Civilian shooters can buy these as military surplus from sellers like Ammo Can Man.
Are plastic ammo boxes as good as metal ammo cans?
Modern plastic ammo boxes from brands like MTM and Plano rival metal cans for indoor storage. They are lighter, cheaper, and easier to carry. The honest difference is impact tolerance: metal cans survive drops and abuse far better. For range day transport, plastic field boxes are ideal. For long-term home storage of bulk ammo, metal cans offer more security and durability.
How do you organize ammo boxes?
Use a clear labeling system: color-coded stickers for caliber, written labels inside the lid, and consistent placement on shelves. Caliber-specific flip-top boxes let you inventory at a glance. For mixed ammo in cans, use cardboard spacers to keep boxes upright and sorted. Inspect seals annually and rotate stock by shooting oldest ammo first.
Final Verdict on the Best Ammo Boxes
After six weeks of testing and years of cumulative use, the Sheffield 12626 Stackable Lockable Box remains my top pick for the best ammo boxes for most shooters. It earned the spot with 27,000+ reviews, a near-perfect 4.6 rating, a real rubber gasket, lockable latches, and stackable corners that fit cleanly in any safe. For handgun reloaders, the MTM P-100 flip-top is unbeatable at the lowest price on this list. For long-term bulk storage in a safe, a metal surplus .50 cal can or the Fortress sealed steel can will outlast everything else you own.
Buy once, label well, drop in a desiccant pack, and store your ammo in a climate-controlled space. Your rounds will be ready when you are, even years from now. If you want a deeper look at larger storage options for a reloading room or armory, our guide to the best ammo cans rounds out the picture.
