Few kits have calipers. I had a chance to pick up some mitutoyo calipers on sale for $100 but went with the Hornady, which are ok. I like the turret press because I only have to screw in the dies once. And the case stays in the press for each operation. To change calibers all I have to do is snap in another turret, different shell holder and go. If I was to get a Rock Chucker Supreme single stage, I would pull the bushing and install the breech lock bushing. That way you can snap the dies in and out. Would make life easier besides being more consistent.
