The MEC Primer Seat Assembly Package (part no. 325CP) is a primer-seating assembly from MEC built for reloaders running MEC shotshell presses. MEC manufactures the assembly in the United States and runs it through the same quality-control process the company applies across its reloading equipment lineup. A properly seated primer is one of the more safety-sensitive steps in the loading sequence, and a well-fitted seating assembly keeps that step consistent and easier to repeat load after load.
