Re: McMillan stock
Sounds like a delay tactic for the smith or maybe he didn't order it for a while after he started. I ordered one three days ago for my wife's 257 Roberts so I really can't help you...yet. Mountain Rifle McSwirly Savage L/A. The guys on the 24 Hour Campfire order them all of the time and I have heard nothing about it taking forever or I would have ordered a Manners S/L Hunter instead.
Machinist are notorious procrastinators with frivilous stuff like a stock, coatings, or such extras. They don't meet time lines very well generally speaking from years of commercial interaction with them.
That is part of their make up and what makes their work so good. If you know the work is going to be first class, check back from time to time to keep your stuff on his radar but you are in too deep now to annoy him.
