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