A few things I've done with shotshell reloading.
►The jigs were made from scrap 4x4, and were cut using a 2" core drill I had laying around from a project.
The shape and size work perfectly with a utility knife.
►As far as load data goes, I talked BPI into letting me preorder their Rio manual, so I may actually have been first to get one.

Great video! I might try this and make 16 gauge mini buck shells for my Model 12.
I recently found a YT video about making the trim guides from EMT conduit. I wish I'd thought of that.
