Seeking input on Dillon Presses

[Touchdown88]

I found myself in a situation where I came across a Dillon 650 and Super 1050 for a good deal. The 650 is setup for 9mm and the 1050 is setup for 223. I already have presses/dies for calibers from 22 hornet up to 375 h&h.

My question is what calibers should I dedicate to the 1050 and what calibers should I dedicate to the 650?

IIRC, the 1050 can only go up to 30-06 length cartridges, but the 650 can go bigger. All things being equal though, I'd probably set the 1050 up for whatever I shoot the most, and use the 650 as the one I swapped tool heads out with more often.
