You can hone the hell out of the chamber with your brake hone and not lose much metal, maybe 0.001-0.002. After you hone try using the brush wrapped with coarse steel wool and dipped in orange rubbing compound like I suggested. Ive done this myself with excellent results.

PS did you dip the brake hone in oil before you used it? You never want to spin it dry.
