In reply to:

There were also some barrel jointing systems that did not employ "welding" at all(i.e brazing/soldering)at all. BSA used a system in which the Chopper lumps were coupled by a vertical dovetail and pinned. This system was also adopted by Winchester on their Model 21 Shotgun.

My post was referring to how the lumps are attached to the barrels, not how the two lumps are attached to each other.

In reply to:

BTW - it's probably a bit misleading in terms of strength to "lump" Monobloc(demi-bloc) barrels in with Dovetail Lumps!




I was not comparing the strength of these systems.
