    I have a barrel from an old Mauser 98, I have just fired 300 rounds throu this barrel.

    Can this barrel be rechamberde to 25 Winchester Super Short Magnum (WSSM) or some other wildcat?

    It is a very good custom barrel and I hope to put it on a different action/project

    If the contour is large enough to set the barrel back enough to "clean up" the Wby, chamber.

    You would have to chop off about 1.5 cm of barrel to lose most of the original chamber & then have the barrel reamed for the chamber you want. Then you would have to rework the magazine for shells of a totally different shape. Sounds plausible, but I don't know if there is anything to gain and a lot of work and/or money involved. You would likely be better off selling what you have & buying what you want, either complete or as components.
