Also, what would be the typical round per hour difference between something like the turret Lee press and a progressive?
Unless you are going through 1k rounds a week I wouldn't even think progressive. I can load around 200 rounds of 45 in an hour on a turret press when I am feeling it, but that is also operating as if it were a single stage. I load several different chamberings and quick changeovers are more important to me than RPH, and that is what I like about the Lee turrets.
