I'm not too familiar with these but if you are running their powder measure on a progresive press does it take the place of the bell die in a 3 die set or does it mount on it like a Lee set up. I see they sell powder through expander inserts for differant calibers. Ultimately I would like to set one of these up on my Lee 4 hole turret. The pro auto disk is good but I think a Hornady set up would be better and easier. I manually index my press now so the exta weight wount be an issue.
