Turning a barrel without adjustable sights

[mark]

I don't own a single action without adjustable sights. When someone has a single action without adjustable sights that shoots left or right of the point of aim, I assume the barrel needs to be turned a little to "adjust" the sight. Am I right so far? So lets say that you have a single action that shoots a great group with a particular load. The elevation is perfect but the windage is off to the right. If a gunsmith turns the barrel, what happens to the ejector rod housing? Does that get "tilted" as well? How about the front sight? Does that stay straight? Does the elevation get effected?
Thanks,

The amount you clock the barrel will be WAY less than what you seem to be thinking it will be.
Great article on the subject:

Great article and thanks for the link. Not sure I understand how turning the barrel that small of an amount makes that much difference but if Bowen says it does, I trust that it's true. Are there equal chances that the movement in POI versus the aiming point could have the reversed effect? In other words, could it make the problem worse?

[Aggie01]

Lets say a sixgun (short barrel) has a 6" sighting radius.
a target at 25 Yards is 900 inches away.
any change made at the front sight is magnified 150 times at the target. (900/6)

so to get a 3 inch change in POI, you move the front sight over .02.

IIRRC Bowen basically says in his article that you loosen the barrel and tighten it back down and go shoot it. He talks about moving the barrel a fraction of a pin punch witness mark at most.

Theoretically, you could make grouping worse if your gun shot to the left and you tightened the barrel to move the front sight and exacerbated a thread choking condition.
Grouping, not POI v POA problems.
The only way I think you could make that worse is if you moved it the wrong direction, got a worse result and KEPT moving it that direction instead of backing up. If that happens, give up sixgunning and go into politics.

Impeccable logic and math, I'd say. Provided your witness marks are good and your judgement of partial pin punch calibrations are too, you almost couldn't go wrong.

Well, actually, I probably could, but that's another problem.
