Good old fashioned Dark Threading Oil works , too (less then $20/gal.).
I use Ridged dark thread cutting oil for chambering and threading.
I cut from .015 to ,030 at a time depending on the size of the reamer (small reamers require more
frequent cleaning and less cutting) and clean with air and wipe the reamer clean.
I also use a high pressure lube on the pilot to keep it from marking the rifling.
For the pressure system any good water soluble oil will work.
