Primer pocket uniformers are designed to ensure that primer pockets are cut to the correct SAAMI depth specifications, cleaning out built up carbon residue from previous firings and squaring the bottom of the primer pocket with respect to the case head. This step is important as variations in the seating depth of the primer can change how the firing pin strikes the primer producing inconsistent ignition. This tool features a preset stop collar set to SAAMI specifications. Reloader simply inserts and turns. Available in large and small sizes. For pistol cases only.
