While realizing we all prefer perfect "Cosmetics", one other option is to simply shoot it "As Is". It is really doubtful it would affect the pattern much, if at all. I did sucessfully repair a buldged bbl once, but it was on an auto-loader & just behind the muzzle. "NO" I did not consider myself in the same class as a "Torch" guy, as I in no way considered this a dangerous repair.
