Dillon CP2000 and 6mm Dasher

I have not, but know a few guys using 650's/750's ... Theres also a few F-Class guys using them as well.

I can't imagine a CP2000 being any better than a 750 for precision stuff.
 
Really, i'm just after case prep. Would like to de-prime and size on first round. Clean. Prime and expand mandrel on second round. Just think the automatic case feeder would speed things up tremendously. Progressive presses are new to me, just trying to gather any information I can before I order something.
