Precision?
Co-Ax or Arbor press. Precision is more the alignment of the die to the shell holder and that is done with a case in the die.
I never understood turrets, as they seem to be more die storage devices and I don't trust C presses--and they are often so darn heavy to make up for being open.
If you are shooting bottleneck cartridges, I would just stick to single-stage presses as I pull every case after sizing to check case length and trim as needed.
If I wanted a turret, it would be an O type press like the Lee with the auto-indexing option.
Personally, I would buy a progressive before that, if higher production rates are needed.
However, we all have our preferences about presses.
