The project, which took 17 months from start to finish, deserves its own article (note: without a pandemic, it would be faster!). The real reason for writing this article is the horror that caught us when we wrote down a complete list of steps needed to make a box... and we wanted to share it to show how complicated simple projects can be.


Anyone who prefers to put the box together alone is welcome to read all the steps and learn from our path.


To provide the final product we needed  to go through all the steps:

  1. Obtain basic measurements (to understood the size of project materials) - Thanks to Phill Steinmetz
  2. Search for strap producers
  3. Design strap model and make order
  4. Search for buckle producers
  5. Prepare buckle model and make order
  6. Search for local (EU) cardboard producers and accurate materials
  7. Search for material alternatives and make order
  8. Make cardboard prototypes by ourselfs
  9. Design metal teeth and eyelets
  10. Make teeth and eyelets prototypes
  11. Cut received straps 
  12. Search for buckles of better quality and make order
  13. Paint buckles
  14. Sew buckles with straps

  26. Bend all teeth parts

Beside classic features that all manufacturers provide - stamps and labels, we produced this packages with extra details such as:

  • steel reinforcing teeth
  • steel reinforcing eyelets for strap
  • custom produced strap
  • correct staples
  • buckles made in Germany
  • correct measurements (±1mm due to manufacture process)

 We know that details matter!


The journey is difficult, but once the product is finished, the use is really wide. Thanks to this product you can finish your collection of wooden boxes, upgrade historical exhibitions, use it for ammunition storage or shooting trainings, organize ammo on reenactment events...




Another amazing aspect is the universal size that fits different ammo types! Suitable for packing ammo:

  • 20 x 15 7,92mm x 58 (Kar 98, MG34/42 ...), total 300 Gewehrpatronen
  • 52 x 16 9mm x 19 (MP40, P38, P08), total 832 Pistolenpatronen
  • 28 x 15 Kurzpatronen 8 x 33 (Stg, MP44), total 420 Kurzpatronen

We know that in German machinery it depends on every millimeter, so we tested how it works with cumulative error of 1mm. Our Tragschlaufe was tested and fits wooden boxes:

  • Patronenkasten 900 - 3pcs OK
  • Patronenkasten 1500 without metal insert - 5pcs OK
  • Patronenkasten 1500 Luftdichter insert - 5pcs are very very tight, but possible




Currently we need to finalize last steps and prepare the dispatching. Sending of preorders is expected on early September (as you already experienced preorders, it could be slightly delayed).

We offer two versions in preordering phase:

1x Tragschlaufe + 20x standard 8x57 ammo boxes

3x Tragschlaufe empty

After preordering phase, there will be available 1x Tragschlaufe empty in the standard offer.
