I know you can open up a boltface to a bigger diameter, but is there away to close it up a bit? The reason I ask is I have a .17 Remington barrel for a 700, and have been told that I can get the threads cut down to fit my small shank Turk. Mauser. I guess they call them turkingtons!
But I have a .473 boltface for the 8X57. Is there anything that can be done here? Thanks
