[QUOTE="tobnpr, post: 2281111, member: 68758"] Removing deep gouges from the chamber walls is more than "honing". If the gouging is deep enough to strip and hold brass- that's pretty deep. A chamber hone is for removing light scratches. I can't tell from the pictures- is the gouging circular as opposed to linear (down the length of the chamber)? Usually circular gouging is caused if the smith begins to withdraw the reamer before the spindle has come to a complete stop. A chip gets caught between a reamer flute and the chamber wall and as it's withdrawn creates a "screw" like scratch in the chamber. I have no explanation for them if they're running the length of the chamber- usually machining artifacts in barrels are circular by nature of the work. Anyway... You didn't mention how the rifle shoots. If it's shooting well, you're not having extraction issues, and if the damage to the brass isn't extreme you don't [I]need[/I] to do anything. The correct "fix" for scratches that deep is to set the barrel back a revolution or two (whatever I need to clean up) and deepen the chamber. This should be done at no charge by the smith that did the work originally- but given that he decided to try to hone them out- and then you had to take it to another smith anyway, probably not a good option.
