The MEC 600 Primer Seating Pad (MEC part no. 331) is a steel spring pad used for repriming your shell on single-stage machines. It’s built as a one-size-fits-all part, so there’s no guessing which version matches your press before you order. Shotshell reloaders running a MEC single-stage setup keep a spare on hand since it’s a wear part that sees a press stroke every shell. Find it in our reloading equipment lineup.
