Guys,
When barrels are sleeved(in Germany),they are drilled/reamed out from the rear to fit purchased barrel blanks, which are of such thickness throughout to withstand the proof pressures.The thickness of the walls of the old barrel stub (hakenstuck),then, would depend on the diameter of the original barrels.All the ones I saw were softsoldered in(the old barrel bundle would have been hardsoldered [brazed]at the breech end only),the joint being large enough that softsolder is sufficient.If my memory is not too bad, the diameter of the barrel blanks in 16 ga are either 18 or 19mm at the chamber end.

On reflection,I think the 18 or 19 mm is the dia at the shank of the rifle barrel in a drilling,rather than 16 ga barrel.
