Here's a dillon progressive, the dillon 650 set up for .223.
Here's a lee turret. set up for 40 s&w
With the progressive you have the tool head,(where the dies are screwed into), that stays stationary. The ram has multiple shell holders or shell plate that rotates under the tool head. On the 650, the shell plate is automatically advanced to line up under the dies. All five operations are done at the same time to all five shells in the shell plate. This results in a loaded shell being produced with every pull of the handle.
In a turret like the lee in the pic, the turret with the dies mounted in it, turns to align dies with a single ram with one shell holder in it. This lee is the 4 hole model and has automatic advance, or can be manually advanced. This requires 3 or 4 handle strokes to produce a loaded round. You also have to handle each primer, case and bullet to load.
The dillon has an automatic case feeder, auto primer feed and powder measure as well as a powder sensor and low primer alert buzzer. All that is required is place a bullet on the mouth of the case and pull the handle.[/img]
