This is impossible as the bore is never straight and only in dreams is it straight based on typical assumptions. The premium smiths will do their chambering and muzzle threading/crowning based on alignment of the bore and deal with the position of the barrel after by indexing at the breech. Low cost muzzle threading operations simply center based centering with a live center off the tail stock (not representative of what the bore is doing).

The better the barrel maker the straighter the bore. Exterior turning is typically done based on an artificial center created when the barrel is supported at two points or the ends.

The better the barrel the sloppier the smith can be as they don't take into account the bore of the barrel when performing their machining operations.
