This 2mm 3D-printable spacer washer allows you to reload 9x21mm cartridges using your standard 9x19mm Luger Lee Dies without ever changing or losing your original die adjustments!
Since the 9x21mm case is exactly 2.0mm longer than the 9x19mm case, placing this spacer under the die body raises it by the precise difference required.
How to Use
Unscrew your adjusted 9x19mm Lee Die from your press (turret or single-stage).
Insert this 2mm spacer washer between the aluminum lock ring / lock-nut and the top of the press frame (or turret head).
Screw the die back down until the lock ring sits snugly against the washer.
You are ready to reload 9x21mm! To switch back to 9x19mm, simply remove the washer.
