repair of model 1886 40-65 chamber|Restoration, Repair and Maintenance|Forum|Winchester Collector

Is it possible to repair/replace or re-chamber a worn chamber on a model 1886 takedown in 40-65. If possible what would a ballpark cost be for this.
The barrel is still good however it appears that someone in its 120 year life did some work on it. The 40-65 cartridge seats in too deep and the extractor
can’t grab it to eject, as well as some play.

I’m looking for recommendations also.

any help would be appreciated

Thanks Dan
