I created these ammo box templates in order to be able to store ammunition in ammo cans efficiently. I determined the sizes according to the capacity of common standard magazines. Clipping them out involves a minimal amount of lines that can be done with a straightedge and a hobby knife, though scissors can be used.

Tips:
- MAKE SURE TO DISABLE ALL SCALING IN YOUR PRINTER SETTINGS. These dimensions are quite precise. That said, your printer make/model may create a slightly larger or smaller box than mine. In that case, adjust your printer scaling until the box matches the dimensions listed in the table.
- Many PDF document viewers support adding annotations or notes to the document, and you can use this to label your boxes with the print.
- I have had success printing these on 199g/m^2 card stock. Stiff enough to hold a good shape, but flexible enough to get through a small laser printer.
- Cut on solid lines, fold on dotted.
- Tapered rounds (like .223) should be inserted in alternating directions, creating a checkerboard-like pattern.
- Taping the box flaps on the outside seems to increase rigidity.
- There is some variation in ammo can sizes. The fit numbers reflect my own personal observations.
