What makes the .50 BMG box special


Caliber-specific fit
Custom-fit slots according to CIP standard dimensions – each cartridge sits firmly in its place, minimizing play and rattling. The shape follows the caliber, not the drawer.


Sliding lid, space-saving
The lid slides open from the side, not flipped up – this saves height and makes the cartridges easily accessible with one hand. When closed, the lid runs in a guide and sits securely.


Stable & durable
Solid construction for continuous use – firm stand in the cabinet, well stored in the range bag, reusable instead of disposable packaging.


Clean labeling
The caliber is permanently marked on the front and lid by laser engraving – in a full gun cabinet, you immediately reach for the right box.



Individually on request
Optional and just to your taste: individual laser engraving (name, club, custom labeling) or a desired color. Contact us – we will customize your box for you.
Custom-made boxes are excluded from the 14-day right of withdrawal – they are made exactly according to your wishes.


For sports shooters, hunters, and reloaders



Reloaders: one box per load (powder type, charge, bullet) – batches clearly separated and distinctly assigned by laser engraving instead of mixed loads.

Sports shooter: one box per discipline or weapon – defined quantity per box, ammunition count at a glance.

Organized supply: uniformly labeled in the gun cabinet, readily available for stand, area, and range bag.



Manufactured in Westerwald

Manufactured in our own production in Westerwald, piece by piece – instead of anonymous imported goods. The 3D printing runs largely on solar power from our own 22 kWp photovoltaic system. Material: Filamelt PLA+ 2.0.


Other variants & complementary accessories

Also available for .50 BMG:


Flip lid (ABox) – fully openable, cartridges readily accessible
Filamelt reloading board



Frequently asked questions about the .50 BMG box


Do my reloading cartridges also fit?
The box is designed for CIP-compliant .50 BMG (OAL up to 138.43 mm according to CIP). Custom loads with longer seating depth (long bullets, shallow seating depth) may be close to the upper OAL limit – if in doubt, please inquire in advance.


Does the sliding lid run smoothly?
htgängig?
Directly after manufacturing, the sliding cover may initially run a bit tight; after a few opening cycles, the guide will wear in. At the beginning, a sparingly applied gun or PTFE grease on the sliding surfaces helps. Minor manufacturing tolerances are possible.

Are the boxes suitable for transport?
Yes. As a storage and organization box, it accompanies you in the Range Bag. However, it is not a safety container in the sense of the WaffG/AWaffV and not an approved hazardous goods packaging.

Can the box withstand heat (e.g., the summer trunk)?
Yes, with normal storage, it remains dimensionally stable. High continuous heat – like in a hot trunk in midsummer – is not suitable for PLA; the box is not designed for that.

What are the tolerances in 3D printing?
In 3D printing, small manufacturing tolerances are normal. This does not change the tight fit of the cartridges; however, a slight play remains due to the design, and the bullet tip is preserved as much as possible.

End of loose cartridges
Choose your capacity for .50 BMG – from the small box for the Range Bag to the large box for storage.

Important notes: Delivery is without ammunition. This box is for organization and transport and is not a safety container in the sense of § 36 WaffG / § 13 AWaffV; it does not replace prescribed ammunition storage and does not have ADR/UN hazardous goods approval.
