[QUOTE="MNbogboy, post: 1737984, member: 18849"] The Marlin has been said to have same threads as small shank savage (1.055x20). If this is true the shank thru the nut is probably close (1.062). One full turn is .050. ...1/8 inch along the barrels circumference will be approximately .002. A straight edge mark with a "sharpie" on the top of the receiver across the nut & recoil and onto the barrel & receiver will get you very close to where you were.(Sharpie marks clean off with rubbing alcohol or kroil) Before you start, remove the ejector pin from your bolt and see how many thicknesses of "scotch" tape(trim with scissors) on the head of your "fired" but not sized brass it takes so the bolt will not close. This will be your benchmark to check for same fit once you are finished. The fired brass should just barely close with one thickness (depends on springback). However, without the proper action wrench or barrel vise and barrel nut wrench damage to your action and nut is at risk. A local gunsmith will have all the tools (including the headspace gauge)necessary and bringing him the rifle disassembled as shown should hopefully only take him a matter of minutes to correct.
