Done a few for tx now although the 15 mm dia gives less of a shoulder than the 16 would,

Concentricity has been pretty good too on most .
They seem tightish in the bore so might need a polish.

As a finished s200 barrel it would need post to rod or collect .
I asked them To chop a 1/2" off the breech so it didn't fit s200 any more

Got no evidence whatsoever and again can't remember why but had strong ideas that these go onto some isp guns

Lately been using v shArp hss to machine to avoid galling more visible under magnification
They sound pretty tough then was going to use a carbide tool, i live pretty close to knibbs so can pick it up . not keen on polishing though, wouldn't want to mess it up.
