Almost a Progressive, but it allows the reloader to maintain easy control over the process. It locks in the stations so you don't have to worry about turret alignment and the use of the breech lock system makes the changeover fast and accurate without buying a tool head for every caliber. The optional inline bullet feed is a bonus speed factor, the built in auto eject adds another speed bonus. There are so many things right with this press that it really is hard to list them all.
