Your description of the process is correct so far. I don't know how measuring, trimming and primer crimp removal can be accomplished on a progressive press. Some progressive owners use a dedicated sizing/depriming press, usually a single stage, to process the brass before loading. Which brings up another thought; I batch load with my Co-Ax and Lee turret (I removed the auto index 4 days after I got the press). For my Garand brass, I size and deprime a batch, anywhere from 50 to 200 cases at a time, then remove the crimp at another time. Later I will measure, trim, deburr. In another session I will prime the cases and now I have a batch of processed, ready to charge and seat cases (I have a lot of primed and ready brass waiting for finishing for all my pistols [upwards of 200 each] and two of my rifles [normally just 100-200]).
Is your time so limited that you are concerned with rounds per hour? You've mentioned speed a few times. One good way to ruin a gun, damage fingers, or worse, is to get in a hurry when reloading. Early in my reloading career I had a squib, I was rushing through a session because I wanted to go shooting now! and forgot to charge a case . That happened once, in 1970 and I've not been in a hurry since. Even when I was working 10-12 hrs per day, I either found time or I didn't reload. Period.
