I've loaded with all of the major brands of progressives. Most any of them without a case feeder will produce between 400-600 rounds per hour. The thing to realize is everything is dependent on a variety of things: Setup, preparation, ergonomics and your concentration/focus.
The more ergonomic your press and bin setups are, the more rounds you can do per hour.
The more organized your bench space is, the more rounds you can do per hour.
The more preparation you do, the more rounds you can do per hour.
The better the ergonomics are on your press, the more rounds you can do per hour.
The more focused you are and the better you concentrate, the more rounds per hour you can produce.
So all things being equal, there's a wide variety of production available from any one of the progressive presses. All brands produce ammo reasonably efficiently for most people. The biggest part of getting production is having the press, regardless of brand, properly adjusted, cleaned, tuned/tweaked and operating it smoothly. You do all those things, you get good production from about any brand. You don't, you won't get good production.
Variable that affect speed are primer brand, brass and bullet size. Other variables are changeover time and prep time. Some brands take more of some things than others.
I have reached a point I want a press that's fairly easy to change over with minimal adjustments and I can leave setup for one cartridge until I've ran off a large number of cartrdiges. This way, I can run off 25 at a time between half time shows, advertisements and such on the tv and never "feel" I've reloaded anything.
And I know if I do my part polishing, tuning, adjusting, loctiting and setting up strong mounts, roller handles, brass and bullet bins, then get supplies ready and in place, then be focused on the process when reloading, the press will do it's part by rewarding me with ease of operation and production efficiency. This will lead me to lots of cartridges:
The big blue bin is now overflowing:
This is 1500 cartridges I reloaded 25 at a time while watching college basketball. Never realized I was reloading it. Never felt it, just did it here and there.
But lots of cartridges isn't the whole story. There's also quality of cartridges produced. You want to slow down and operate your press in such a fashion as to produce quality cartridges. Producing quality cartridges leads to accuracy. Accuracy leads to shooting satisfaction.
