If I was starting with a new body as Geoffs thread 11, then I would assume that it is just that, new with intact locking shoulders. But if I was starting with a well used - or ANY other body I'd start by putting a suitable stub-end of an unserviceable barrel in seeing how that CHS'd. If it went well with a 0,1 or 2 then carry on with the new made barrel. But when you're getting to a No3 bolt head, the REME inspectorate knew a thing or two about end-of-life expectancy when they decreed that a No3 bolt head could not be used as a standard at Base workshops.
These are only my views of course and look forwards to a long discussion on the subject..........Information
