Abstract
A system for improving the accuracy of the seating of primers in primer pockets of shell casings while avoiding damaging the end of the shell casing is provided. A stop mechanism that directly engages the bottom of the shell is included such that, as the primer is inserted into the primer pocket, more accurate seating depth is ensured. In addition, the seating depth may be adjusted in order to compensate for changes over time, which may be due to changes in materials or wear. Further, components that interact with the end of the shell casing and rod have increased thickness to add strength and provide more surface area relative to the base of the shell casing, thus reducing the chance that the base of the shell casing is bent and allowing for a precise stopping position during priming.
