When using a Lathe fitted with the system that pumps cutting oil down the Barrel and over the Reamer, do you have to order a special Reamer and\or Pilots to allow the oil to pass over it?
Thank you.

The 'rifling' isn't enough. It raises pressure without allowing volume. Ya' need the 'oil grooves', like J E said. I manage to get about 35psi goin' before I have leaks at the muzzle. (I have 'oil grooves') I've got $160 in my 5 gal. coolant tank, SO NO LEAKS! The smaller the caliber the quicker the pressure climbs. (I've got alot more pump than what I need!)I'm not a gunsmith but it seems the rifling would allow fluid to flow around the pilot.
