It looks like there is 3 1/2" clearance from the top of the shell plate to the bottom of the turret carrier, so you should be able to do .30-'06 but it might be close. .308, .243, .223 should be no problem.
For caliber switches, I set up a turret for each caliber and leave it alone, as well as a shell plate and carrier with the correct primer size so that caliber changes are as easy as possible - remove the turret, remove carrier w/shell plate, install new carrier w/shell plate, install new turret, done. Takes a couple minutes, and no adjustments needed (after setting the caliber up the first time, of course).
If you need to save a couple $$, you can just switch shell plates and save the price of a carrier - saves about $35 per caliber once you have both small and large primer carriers, but takes another couple of minutes to make the switch. Same for the turrets, save about $11 per caliber and switch dies each caliber change and add a couple of minutes.
