I think everybody that has decided on ways to get it done, struggled some with finding what seemed right to them.
I know two smiths who are 180 degree opposite about whether to fit a rem bolt nose .001 fit to the barrel counterbore, I listed to both, but the one guy told me he does not want the bolt nose touching anything ANYWHERE, and it rung true with me and I now use .01 in every direction to make sure it never does.
Reading through Rifle Accuracy Facts by Dr. Harold Vaughn taught me a LOT....has me going NO NO NO when people talk about stiffening up receivers with beefy scope mounts screwed on top. Saw it in reference to a Muzzle loader build on a savage action and reasoning told me "the reciever ring is not in tension when it fires, no issue there".
Anybody that can find a copy of that book is encouraged to read it from cover to cover.
