Precision Primer Gauge

Precision Primer Gauge

The Accuracy One Precision Primer Gauge is a tool set designed to make precision measurements of primer pocket depth and the depth of seated primers in relationship to the face of the case head.

The Precision Primer Gauge can also be used to measure the thickness of an unseated primer, allowing you to calculate the optimum seating depth for the particular primers and cases you are loading.
