When I am going to put out a lot of ammo, say for SASS or for Varmint Hunting, I use the progessive and turn out one round for every pull of the handle. On a turret press, you will save time if you do one cartridge at a time, but I do batches so I don't have to change the dies much. On these, you will have to pull the handle 3 to 4 times per cartridge.
