Hi all, I`m having problems with my cut rifling of 4140 blank barrels, ,45 cal. I use a T/C cutter at 5% forward angle in cutter box on a sliding ramp , coolcut cutting oil and pull through by hand. The problem is cutter rips small chunks and leaves scratch's in the groves, so that am I doing wrong, would love to get a nice smooth finish in the rifling, , help. Homebrew.357.
