    Now that’s interesting.  Not a far fetched theory in my neck of the woods.

    A Winchester barrel should be stamped Winchester Special Smokeless Steel on the side. At least for pre 64'.

    I have a muzzle loader that I fired with dead air between the powder charge and the projectile. A serious wrong that I should have avoided since I knew better. There is a spot in the rifling thats loose on an otherwise tight patched round ball. No effect on accuracy I can detect and no indication of a ring on the exterior.

    Theoretically, the propellant in a 300 Weatherby should be buring progressively. Creating increasing pressure until the bullet exits the muzzle. Shuch a condition could conceivably create a ring from many different causes that might alter the bullets dwell time.

    It is stamped.  Originally it was a 300 Magnum as stamped on barrel but many such guns were “converted” to .300 Weatherby by rechambering when the Weatherby were hot in the market.  Another plausible theory.

    My limited references show only 300H&H or 300WM as pre 64' factory chamberings.

    I'm pretty sure post 64' M70s were factory chambered for 300Weatherby.

    The 300 mag pre 64s are a bit scarce. Likely no one anticipated that before reaching for the radius shoulder reamer.

    Yep, crazy right?
