I have been made curious concerning the exact method of attack in removing warpage interference from a recased action. Matter of cold-bending here; bit of light reaming there; a salutary tippy-tap in between? For that matter, how does correction differ from the process of jointing or rejointing a gun with removable hingepin or from the cottage industry process of dressing down a shimmed hook to put an old gun on face, or more aptly perhaps, with the breech ends of its barrels back "at the face"? I know Oscar found some sort of fixtures or retainers a desirable addition to the bar before it went in the charcoal pack. One would guess he didn't think a warped bar was very easily corrected. Perhaps someone could give us a primer, or barring that, we could have one of our blind men touching the elephant discussions until we produce a vaguely mammalian shape.
