Any boring bar small enough to bore out a barrel is going to vary with tolerances when push it out over 5 inches. You will be limited to drilling honing the ID at 9" and that can be expensive as the tooling is pretty specialized. Someone who can make full length one piece barrels could do it but most places with that type of machinery usually dont do small runs so if they did it would be big bucks, real big.
