Another aspect to an accurate rifle is how the barrel is aligned to the lathe prior to threading and chambering (with the barrel through the headstock). I used techniques that some 1,000 yard benchrest shooters use where a cylindrical section of the barrel, where the bullet would lie when chambered, is made to run absolutely dead-nuts to the lathe's center. This is done with a long-pointed, 1/10,000" reading dial-indicator. You then drill, taper-bore and the chamber ream with a floated reamer.
Having a good chamber/reamer design, and also a bullet design to fit, also aids in accuracy.
How you then crown the muzzle, using the above mentioned technique, for getting a section of the bore to run absolutely dead nuts, is also critical. I also left my crown square and sharp, with no bevel, as some 1,00 yard benchrest shooters do.
This is a lot of work to do and difficult to find a gunsmith willing to do it, so I had to teach myself how to perform.
These gunsmithing techniques may not aid accuracy when shooting lead bullets with black powder, so I was told by many, but it didn't seem to hurt in my case.
