A lot of the reason for reloading is about doing something interesting. I can’t imagine any reason for using the stuff we’ve been seeing here as a sole way of loading shotguns short of running ahead of the Zombie Apocalypse. OTOH, it looks like it might be interesting to try.
About a year or so ago, I got s similar set of odd tools that S&W made around the turn of the last century for 32 S&W cartridges. I loaded a dozen or so just to prove I could, but haven’t used them any more since... I use my “modern” Lyman 310 tool instead!
