    Due to the communications about the posting on another thread, I thought that readers might be interested in a specifically titled thread to ensure that everyone has the opportunity to enhance their understanding of what is possible in the realm of gunsmithing. The tale is in the pictures.

    Here is what I posted earlier regarding a proper repair of a bad chamber.

    ------------------------------------------------------


    I have done this type of repair and have some views that may interest the reader.

    This is one Superposed with eroded chambers that needed new chamber contour to reduce shell grab and improve extraction, plus the owner hated the appearance and wanted a change. The 2 different views make the erosion/pitting level apparent, and the "after" views make it clear that the finish is close to what you expect to see in a brand new Browning chamber.

    In other words, this is not a utilitarian chamber sleeving meant to renew the serviceability, but is also intended to be cosmetically imperceptible from a normal chamber. Naturally, this requires specialized effort to make such results, but a quality gun needs a quality job. This example had a better appearance inside the chamber than the rest of the bore after completion, so then there was some mismatch in the opposite way vs. when it arrived from Art's.

    This type of repair is also done for overall renewal, reset of the rim depth in cases of excess headspace/misfires, improved rim contact to an extractor due to extra side play available for the cartridge, and can even make some difference of offset (another misfire condition) firing pin hit location on the primer.

    This should provide sufficient information of the improvement to discern if the job was properly completed and cosmetically acceptable.
