Thanks for the reply. The insanely high pressures were safely worked up many years ago when speed was king by a friend of mine. In truth i dont know what constitutes a "high pressure," i only know we were clocking 180 grainers at 1850 fps out of that smith.
Do you (or anyone) have any suggestions on how to properly polish a cylinder? From what i read it involves JB polish and slow turning patch-wrapped brushes in a drill...
