Practical rate on a ss press from scratch is about 75rd in an hour. That is everything ready to go & using a powder measure that has the charge wt verified.
Why many of us have gone to a progressive for pistol ammo or 223. I started on a ss press 40yrs ago. Today, no way I would recommend that to a pistol shooter. A minimum would be a LCT, but even that will be outgrown once you hit like 300 a week.
