    Barrels from the same production run should perform similarly, but like any process, there are slight variations from part to part that are within acceptable tolerance and perhaps a few outside tolerance that should be caught and corrected in QC.

    The variables are almost to numerous to mention, but broadly speaking, they are:
    the blank
    the machining fixturing
    chamber tooling/gaging
    crown
    lining/coating

    Large differences in one or many of these areas are probable between two different barrel makers. Just changing blanks can produce differences.
