I have no experience with turret presses.

What is the proper method for use?
Put a brass hull in the shellholder and run it up and down as you rotate the various dies around to size, expand case neck, dump powder, etc., then remove the hull from the shell holder, or run all the brass through for one function at a time, and only rotate the turret when moving on to the next operation?

I guess I should say that I know either method will work, but what is the most common method?
