Ok be gentle... 
But could you use the exact same chamber reamer that cut your chamber to remove the carbon ring?
Say that you tapped the end of the reamer 8/32" and attached a short chamber cleaning rod and gently turned it in the chamber with a fine layer of oil on the reamer? Would that scrape out the carbon ring in one twist?
Too risky, won't work?
Thanks
