I've been hard at work designing, prototyping, and testing four new punches to produce full-sized wads for 20G and .410 bore, as well as filler wads and overshot cards for both of these.

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.

I've designed and manufactured my own custom punch for producing 12 gauge filler wads and overshot cards.  The model shown in the video represents my prototype, which I've been using and testing for quite a while now.
