And I think that the barrel could be cut / set back one full turn, and at the same time cut (as large a radius as possible?) slightly forward as well? And then a spacer cut and pressed on to replicate the shoulder and flange area, and install and profiled same as the original concave radius and flange? It would be like a two part barrel?.... all it has to do is re-index correctly and tightly, and also have the extractor and feed ramp recut, and be re-chambered to close on the "GO"... I could accomplish that?
It wouldn't be perfect, but I bet it would work?.... Anyway, some better than .020" too deep on the breech end??...
.. Best to you, til...lat'r....GT .....
