12G Shotshell Filler Wad/Overshot Card Punch – Completed!

Back in late 2017 I began work on a press-mounted tool for punching my own shotshell filler wads and overshot cards.  After an initial prototype and two revisions, I'm happy to report it's finally complete, and in production. Today I'm going to walk you through the final version, including the features and construction, as well as an explanation of how it works.
