David, I have known people that use polishing compound, emery paper and even toothpaste on their raceways to slick them up, but I believe I have a better suggestion. Put up 4 dummy rounds at maximum OAL for a Federal. While watching tonight's football game, continue to cycle the rounds through the rifle, and I'll bet by the third quarter you will notice a difference. The problem with the compounds is that you stand the risk of getting it behind the lugs and possibly creating a head space issue by lapping them. A lot of folks use various polishing compounds without any issues, but if the rifle is already barreled, I won't use them. CP.
