So many pubs say, "don't swap bolt assemblies between rifles," or else, or else, or else!

Well, why not? Does a "worn down" bolt fail to properly lock with a new barrel? Does this affect anything more than accuracy?

And is there anything wrong with using a new bolt in an older barrel?

Thanks.

if the bolt is not head spaced correctly the gun blows up

Changing bolts can increase the wear on the bolt and locking lugs - until they 'mate up' - then if you switch again the 'mating' process begins anew..

Yes if the bolt is worn far enough headspace could increase to dangerouse levels, but it would have to be a LARGE amount of wear (see Hatcher's Notebook for more information on this subject).

Nothing - in fact it's the first 'fix' you are supposed to attempt when your current bolt + barrel fail the field gauge test.
