It seems that "everone" has a t/c 50c barrel laying around, at the same time it seems that "everone" wants a 40c or 36c barrel. Why can't you have a t/c 50c reamed out and a 40 or 36 or 32 sleve put in. Don't they to this on some of the older CF's?? Slap the barrel with breech plug still in, in lathe, reamout, cool down sleve and heat up barrel, slide in place, cut and crown? There has to be a good reason this is not being done!
