My measurements show that the magazine dovetail would show if a 26″ is cut to 22″. It would have to be cut down to about 21 3/4″ to remove all the dovetail. Is this correct? Also My 1907 made 22″ Short rifle has a muzzle diameter of about .670. My measurements of a standard 26″ barrel rifle shows it to be about .720 at the 22″ point or .050 a much Larger diameter. But…. my 22″ short rifle is 1/2 round and 1/2 octagon so this may affect things.

I am trying to determine if muzzle diameter can help show a rifle was factory made, not cut down. And also to see if a cut down 26″ must be shorter than 22″ to get rid of the tube hanger dovetail which my measurements seem to show.  

Yes, 4.25″ of a standard length barrel would need to be cut off to completely eliminate the milled rotary cut for the magazine tube retaining ring.  Muzzle diameters can be used as clue, but are not as clearly defined as the milled front sight dovetail location.
