I am wondering, on the 10/110 can the barrel be threaded in to make "snug" contact with the bolt head, then head space set accordingly, or is there a prescribed amount of "clearance" that is needed. I have not had a Savage apart recently (rebarreled many 100's of rifles over the last 30yrs) and am about too.

My thinking on this would be in swapping barrels, they can be run in to make contact, tighten the nut and pull the trigger. Makes sense to me, but so do lots of wrong things.
