Thanks AzShooter.
I found a place on the internet where you can rent the whole cutter and bushings for $30.00. Do the job and then send it back to them. I will probably let S&W do the work but if they bulk at it I will rent the cutter and do it my self. AZ, how far did you go down with the cutter. I have never done it or even checked on it as of yet so I am wondering do you go half way approximately or do you go till you can barely feel it touch the rifling ?
