There is considerable discussion on the different shooting forums about the use of colloidal graphite, i.e. Lock-Ease. Most of the discussion is around barrel break-in. However I have found that a saturated patch down the barrel after cleaning has settled down my clean bore shot. Lock-Ease's carrier will evaporate leaving only the graphite.
