Case-prep is going to be the biggest sticking point with your desired output, especially because you're starting with brass with crimped primer pockets (
).
At the minimum you'll need to size, swage, trim and chamfer. If you're really picky, you'll probably want to deburr the flash hole too. You'll want a Giruad trimmer and a Dillon Super Swage. Luckily swaging is a one-operation, as is flash-hole deburring. Trimming only has to be done every 2-3 loadings.
Depending on your powder measure, you may not have to weigh your 600-yard loads. I'm knocking on the door to High Master (if I shoot a 780 at my next match...) and I have NEVER weighed a charge for 600-yard ammo. To compound the horrors, I run either Varget or RL-15 through a LEE Perfect Powder measure into my .223 cases!
Oh, I also run Nosler bullets because I can find them for less money than the Sierras and Hornadys most of the guys I shoot with use...
All that said, 200-rounds in 90 minutes is doable on a single-stage, but only if you start with cases that have been prepped (sized and trimmed). I prefer to treat these as two separate things: One night I'll prep the boxes of cases I want to reload, and then the next I make them into live ammo.
