I'd never thought of using a turret press for one operation, for a batch of cases, at a time. Changing dies, especially when using the Hornady bushings or a Co-Ax arrangement takes almost no time...I have the InLine Fabrication die holders on my Ultramount which make it even easierI thought the idea of turrets was to save time changing dies, not so much to use them like a progressive? Do one individual step on every case, advance to next die, do that step to every case, etc.
I always thought the advantage of a turret press was that you would perform all the steps need to produce one completed round at a time so that you could stop at any point and not have a number of partially processed cases.
