This is for the "smiths" out there. When you are re-barreling a rem. 700 what tolerances do you leave: - From the outside of the bolt head to the inside of the barrel recess? - From the front of the recess to the front of the bolt? - And, from the back of the barrel to the front of the bolt lugs? Just curious if you all have a set standard or not and why it is what it is?
