Dewey, thanks for the additional details.

No doubt Winchester's (and other gunmakers') marketers puffed up their product feature claims into the hype stratosphere. And I have no basis to question your assessment of the methods of joining chopper lump barrels. But I tend to think (we can only surmise) that the guys who designed and built the 21 believed the additional machining to create the dovetail joints made a stronger joint than simply soldering flat lumps. BSA had done it before, and Winchester liked to say they borrowed what they considered the best features of others' guns.
