Key factor boring and reaming any hole is the set up. When you put the work in the lathe it has to be dialed in so the cutter will run true. Problem with higher quality older doubles is they are not straight. Barrels held together with wire and moved with wedges while the gun was regulated and patterned. Builder satisfied he laid the ribs fixing the barrels. They may be straight may not be.Quality judged by point of impact and pattern.
100 years later machinist has a order to work on the barrels, how is he going to set up. Is it straight or out a few thou half way, just in front of the chambers. or near the Muzzles. Wall thickness at the muzzles is small & your eye can see out of round easily. 100 dollars fee hes going to set up close to the muzzle so it looks right and wont take a lot of time.
How the gun patterns is not part of the job and few customers will check the work on paper. If he hits targets confidence goes up and is pleased with the work. Not arguing against opening but you get what you pay for and may not be happy with quick inexpensive work, or may be delighted.
