I'm not sure what you want to do is really worth all the trouble. I use a Lee 3-holer and I've toyed with that idea and more. I rigged an automatic primer feeder on it that worked but was a bit of kludge to use. I mounted one of the Lee Perfect Powder Measures on a Lee rifle charging die and it worked too, but again, it wasn't really worth the trouble.
When I load pistol ammo, I really like the auto-indexing feature and use it to turn out a lot of ammo in a short time. When loading rifle ammo though, the auto-index wants to turn the turret before the case is clear of the die, making things bind up and come to a grinding halt. I'm told that this isn't a problem with shorter rifle cartridges though, so you may be ok.
I don't load much "blasting" ammo, having been bitten by the long-range target bug. So I generally use my turret press more like a single stage press but with all the dies pre-set. I de-prime the cases and then tumble them. Then I clean the flash-holes and prime the cases with an Auto-Prime. The old, tried and true Perfect measure still cranks out loads within 1/10 of a grain all day long, so I use it to charge the cases and then make that final check with a flashlight to see that they all have the right amount of powder in them. The final act is seating the bullets after which I go out shooting so I can start all over again.
I'm not a great believer in automated loading, but if I were I think I'd just go ahead and buy a Dillon. Those who own them swear by them. Me? I like Lee.
