Your problem on something like a 650 will be changing between small and large primers, which takes a bit longer.
I load 3 different pistol calibres on a 650 and switching between calibres with dedicated toolheads makes things faster but they're all small primer. If I read correctly, you'll be loading 9 mm, .45 and 10 mm. Changing will/might require a different dedicated toolhead, different shellplate, different station locator, different locator buttons, different body bushing, different case arm bushing, different casefeed adapter, different casefeed plate and completely swapping out the priming system if you're going from small to large or vice versa. I'm not sure how everyone else is doing this in 90 seconds.
With all that said, I think you're too concerned about the time it takes to change between calibres, but that's your prerogative. Once my 650 is setup, I can pump out 1K rounds in ~1.5 hrs. In my opinion, and it's just that, speed matters much more when loading pistol rounds. While you're fiddling around with a turret press, I will have loaded all my rounds and BBQed a few steaks. You're just displacing time from setup to loading, again, just my 2 ¢ (probably not even worth that).
I sure can't swap out a 750 in 90 seconds but the toolhead is a couple of seconds (assuming you have a dedicated powder measure) The shellplate is a few minutes to remove, install, check for proper operation and lock it down. The bushings/locatorsetc can be done in a few minutes too. The priming system from large to small can take a few minutes but it's not really complicated once it's been done a few times. Maybe 15 minutes to do it all? I guess I lied on my first post, I was thinking about just the toolhead and shellplate.
I agree 1000 rounds in 1.5 hours is certainly doable.
To me, going with a progressive is about having lots of brass and components and loading a big pile of ammo before swapping to another cartridge.
I find priming and primers in general to be the most finicky part of most progressives, and causes the most stoppages so these days I break loading down into 2 steps. Deprime using a FW spring loaded decapper which gives almost 100% positive decapping, then priming and case sizing. Then run primed and sized brass through the case feeder and because I already know all the cases are properly primed I don't worry about a primer seated too high or a missing primer. Charge with powder which expands mouth, bullet feeder drops the bullet then seat and crimp. This greatly reduces annoying stoppages, which I find to be the biggest time waster with progressives.
