    If it was a .25-06 the shorter, slimmer .22-250 would chamber.

    Could be any number of calibers..or just something that some unknown ground out and chambered.
    The proper method to determine the chamber is with the low temperature alloy Brownell's sells.

    The barrel is plugged just forward of the chamber.

    One melts the Cerrosafe in a clean ladle (150-190 degrees) and pours it in the chamber. Heating the chamber a bit ensures a wrinkle free cast.

    Upon cooling, the stuff shrinks slightly, allowing the cast to drop out of the chamber.

    Measuring various points of the cast soon tells the story about caliber.
