Probably relevant to the discussion, and cutting threads for screw in tubes.
https://parkerguns.org/forums/archive/index.php/t-43714.htmlVic Venters shared that David Dryhurst told him that cutting choke in crolle tubes was more difficult in that the metal would occasionally fracture.
This may be why Briley only installs permanent tubes.
That’s not true. Not too long ago (within the last couple of years), I refinished a set of Lefever Damascus barrels for a member here that Briley put thin walls into.
I’ve refinished a couple of different sets of Damascus barrels since then that also had Briley thin walls installed.
