When I load up rifle, I still use single stage (for everything but my AR anyway).
Honestly, 50 - or possibly a few more - per hour is about right. But when I'm loading this way, I'm loading for quality first, consistency second and everything else third.
I really don't think it's wise to get hung up on production numbers. Even on my LnL, I bet I don't push more than 200 or possibly 250 an hour of plinking ammo, and that's probably realistically on the high side. I tend to view the bragging about production numbers like I do when folks talk about their diesel truck mileage - lots of inflating going on. And I wonder about their QC in the process and hope I'm not standing next to them on the range when a KABOOM happens.
That's just me though, but quality over quantity every day of the week and twice on Sundays.
