Reloading gear needs storage that won't rust, won't shift on the bench, and keeps damp off primers and powder. This guide ranks six ammo boxes built for exactly that job, from a £15 tin to a £55 steel Laycorn box, so you can match the tin to your bench setup in 2026.
- Brand New 50 Cal Ammo Tin wins overall for ammo boxes for reloading storage at £15 — buy it for most benches.
- Genuine British Military Laycorn Steel Storage Box holds the most volume at £55 for bulk brass and powder.
- L17A1 Medium Calibre Ammo Box stacks cleanly for component organisation at £25.
- Genuine Military Tall 50 Cal Ammo Tin (Grade Used) is the £15 budget pick when seal condition matters less than price.
- Every pick here is genuine MOD or military surplus issue, not a replica tin.
Why this matters
A reloading bench full of loose brass, powder tins and dies is how you end up with a corroded press or a spilled hopper. Genuine surplus ammo tins were built to keep ammunition dry and stacked in a field depot — the same rubber gaskets and steel gauge do the job on a bench just as well as they did in a magazine store.
Plastic ammo cans crack at the hinge after a few winters in an unheated shed. Steel doesn't. If you're already running a webbing pouch setup at the range, the military ammo pouches for shooting range and reloading kit guide covers the carry side — this one is about what sits on the shelf behind the press.
Condition grading matters here more than most categories. "New" means unissued, "Grade A" means light service wear with a working seal, "Grade Used" means dents and paint loss but a sound body. None of that is marketing spin — it's what you're actually buying.
What makes the best ammo box for reloading storage
- Seal integrity — a working rubber gasket keeps damp off powder and primers
- Steel gauge and weld quality — thin stamped steel dents; MILSPEC gauge doesn't
- Stackability — modular boxes save shelf space on a cramped bench
- Condition grading — new, Grade A, or Grade Used, stated upfront, not glossed over
- Size match — a tin sized for 50 cal ammo may be too narrow for tall dies or press parts
- Genuine issue vs replica — original MOD or foreign-military manufacture, not a reproduction

1. Brand New 50 Cal Ammo Tin: best ammo box for reloading storage overall
This is the tin most benches actually need — genuine military-issue, unissued, and small enough to fit under a shelf. The rubber gasket seals tight, and the steel body handles being dragged around a workshop without denting.
Brand New 50 Cal Ammo Tin pros:
- Unissued condition, no prior dents or rust spotting
- Working rubber seal keeps powder and primers dry
- Genuine military manufacture, not a repro tin
Brand New 50 Cal Ammo Tin cons:
- Single-unit capacity — buy more than one if you're storing several calibres separately
- No stacking rail, so you're relying on flat-stacking on a shelf
Brand New 50 Cal Ammo Tin pricing: £15 each, sold as new-condition stock.
Best for: the reloader who wants one solid, sealed tin without paying for extra size they don't need.
Verdict: Buy.
2. Genuine British Military Laycorn Steel Storage Box – Grade A: best for bulk brass and powder
The Laycorn (Lacon) box is a genuine MOD-issue side-opening steel container built for modular stacking, and it's the biggest capacity option on this list at £55. If you're storing bulk brass, multiple powder tins or spare dies in one place, this is the box that swallows the lot.
Laycorn Steel Storage Box pros:
- Side-opening design makes it easier to load than a top-lid tin
- Modular stackable body, genuine MOD issue
- Grade A condition — light service wear, fully functional
Laycorn Steel Storage Box cons:
- At £55 it's the most expensive box here
- Takes up more bench or shelf footprint than a standard tin
Laycorn Steel Storage Box pricing: £55, Grade A condition.
Best for: reloaders consolidating several smaller tins into one bulk unit.
Verdict: Buy if bench space allows it.
3. L17A1 Medium Calibre Ammo Box: best for stackable component organisation
Built to MOD Drawing No. SV575A, the L17A1 is a precision-engineered medium-calibre box designed to stack cleanly in a depot rack — which translates directly to a tidy reloading shelf. It's the middle ground between a small tin and the bigger Laycorn box.
L17A1 Medium Calibre Ammo Box pros:
- Genuine MILSPEC manufacture to a stated MOD drawing number
- Stacks predictably, good for separating calibres or component types
- Mid-range price at £25
L17A1 Medium Calibre Ammo Box cons:
- Medium-calibre sizing means long components or full-length dies may not fit
- Less capacity than the Laycorn box for bulk brass
L17A1 Medium Calibre Ammo Box pricing: £25, brand new genuine surplus.
Best for: reloaders who want organised, stackable storage without going oversized.
Verdict: Buy.
4. PA156 Large Metal Mortar Ammo Box: best for oversized dies and press parts
Originally sized for mortar ammunition, the PA156 is an over-sized MILSPEC steel container that happens to be exactly the right shape for long die sets, spare press parts or bulky calibre conversion kits that won't fit a standard 50 cal tin.
PA156 Large Metal Mortar Ammo Box pros:
- Genuinely oversized — takes long or bulky items other tins won't
- Heavy-duty steel to full MILSPEC standard
- £20 price puts serious capacity within reach
PA156 Large Metal Mortar Ammo Box cons:
- Heavier to move once loaded
- Gasket coverage isn't as tight as the 50 cal tins on this list
PA156 Large Metal Mortar Ammo Box pricing: £20, brand new genuine surplus.
Best for: storing dies, conversion kits or press spares that don't fit a standard tin.
Verdict: Buy if you need the extra room; skip if your components are all small-calibre.
5. Genuine US/Italian 50 Cal Ammo Tin – Grade A: best for collector-grade display storage
This one's the near-mint option — a genuine US/Italian 50 cal tin graded A, with a waterproof rubber seal and condition good enough to sit on a display shelf as well as a bench. If cosmetic condition matters to you as much as function, this is the pick.
US/Italian 50 Cal Ammo Tin pros:
- Near-mint Grade A condition
- Waterproof rubber seal, fully functional
- Genuine military issue with clear origin
US/Italian 50 Cal Ammo Tin cons:
- Same £15 price as the Brand New tin but you're paying for cosmetics you may not need on a working bench
- Same single-unit capacity limitation as other 50 cal tins
US/Italian 50 Cal Ammo Tin pricing: £15, Grade A condition.
Best for: reloaders who also collect militaria and want a tin that looks the part.
Verdict: Hold unless the collector-grade finish specifically matters to you.
6. Genuine Military Tall 50 Cal Ammo Tin – Grade Used: best budget option
Grade Used means dents, paint wear and a body that's clearly done a tour — but the tall shape takes long components standing upright, and at £15 you're not paying a premium for a tin you're going to drill, paint or bolt to a shelf anyway.
Tall 50 Cal Ammo Tin (Grade Used) pros:
- Tall body fits long components upright, unlike standard tins
- £15 price for genuine steel construction
- Good candidate for bench-mounting since cosmetic condition doesn't matter
Tall 50 Cal Ammo Tin (Grade Used) cons:
- Dents and paint wear from prior service
- Seal condition should be checked before storing anything moisture-sensitive
Tall 50 Cal Ammo Tin (Grade Used) pricing: £15, Grade Used condition.
Best for: the reloader who wants a working tin to modify without worrying about marking it up.
Verdict: Buy for utility use; skip if you want a tight seal for powder storage.
How we ranked
Each box is judged against the six criteria above: seal, steel gauge, stackability, stated condition grade, size match, and genuine issue over replica. Pricing is quoted from current stock, and condition grading is stated exactly as listed — new, Grade A or Grade Used — because a reloader storing primers cares about that distinction more than most buyers.
“If the tin doesn't seal with a working rubber gasket, it's not built for damp bench storage.”
Which ammo box should you choose?
For most reloading benches, the Brand New 50 Cal Ammo Tin at £15 is the right call for 2026 — sealed, genuine, and sized for the job without excess. Storing bulk brass across multiple calibres, step up to the Laycorn Steel Storage Box at £55. Need somewhere to stash dies and press spares that won't fit a standard tin, take the PA156 Mortar Box at £20. If you just need a working box to drill and bolt down without worrying about scuffs, the Tall 50 Cal Tin, Grade Used, at £15 does the job and nothing more.
FAQ
What's the best ammo box for reloading storage in 2026?
The Brand New 50 Cal Ammo Tin at £15 is the best all-round pick for 2026 — unissued condition, working rubber seal, genuine military manufacture. Bigger benches storing bulk brass do better with the £55 Laycorn Steel Storage Box.
Is a genuine military ammo tin better than a plastic ammo can for reloading?
Yes, for long-term bench storage — steel doesn't crack at the hinge the way plastic cans do after repeated use. A genuine surplus tin also carries a proper rubber gasket seal rather than a snap-fit lid.
How much does a decent ammo box for reloading storage cost?
Genuine surplus ammo tins and boxes run from £15 for a standard 50 cal tin up to £55 for a larger modular steel box like the Laycorn. Mid-sized options like the L17A1 sit around £25.
Can you stack ammo boxes on a reloading bench?
Yes, modular boxes like the Laycorn Steel Storage Box and the L17A1 Medium Calibre Ammo Box are built to stack, which is why they're listed separately from single-unit tins on this page.
What's the difference between Grade A and Grade Used ammo tins?
Grade A means light service wear with a fully working seal and body. Grade Used means visible dents and paint loss but a sound, usable container — check the seal before storing anything moisture-sensitive.
Are surplus ammo boxes waterproof enough for powder storage?
Genuine tins with an intact rubber gasket, like the 50 cal and Laycorn boxes on this list, are built to keep contents dry. Grade Used stock should have its seal checked first since wear can affect the fit.
What size ammo box do I need for reloading dies and components?
Standard 50 cal tins suit brass, primers and small components, but full-length dies and bulky press parts fit better in an oversized box like the PA156 Large Metal Mortar Ammo Box.
Is it legal to buy surplus ammo boxes in the UK?
Yes, the ammo boxes covered here are inert storage containers, not restricted items, and are sold as genuine ex-military surplus for storage use.
One last thing
Don't buy Grade A or near-mint condition if you're planning to drill mounting holes or bolt the box to a shelf — the Tall 50 Cal Tin, Grade Used, at £15 is built for exactly that kind of modification, and paying more for cosmetic condition you're about to ruin makes no sense in 2026 or any other year.
