9x21 Cartridge Headspace Gauge – Case Length Gauge

9x21 Cartridge Inspection Gauge – Case Length Headspace Gauge

The 9x21 case gauge is a reloading inspection tool that allows you to verify the chamberability of 9x21 cartridges once completed. It replicates the dimensions of the cartridge chamber and allows you to quickly identify, before heading to the range, out-of-tolerance ammunition that could cause jams or failure to go into battery.

Checking is simple: the finished cartridge is inserted into the gauge and must slide in freely, with the case head positioned within the minimum and maximum limits indicated by the gauge. This allows for checking the headspace, case length, and external case dimensions in a single operation, highlighting incorrectly resized cases, deformed case mouths, or improper crimping.
