My guess is that there are more guys with a lathe in Montana that know how to cut tenon, threads, chamber, and headspace, than there are small towns in Montana.
Just stick your head out the window of your house and yell, "Who can chamber my rifle?"
I have helped move two lathes to a town of 250 people in Montana, and I know there are better gunsmiths [ones with web sites] than those two in that town.
Google does not show a gunsmith within 200 miles of where I took those lathes
