Glen8338, this is a late response to a secondary question you posted on this thread almost a month ago, that I meant to answer at the time but forgot.
Hope your problem is solved! I'm from Canada and was hoping to not hear of the hassle you are having with Canada warranty service.
Weatherbyman22, this tightening the rear guard screw before the front guard screw is new to me. My mentor, God rest his soul, informed me to snug both guard screws up! but torque the front first and then the rear. I have done this for 50 years on all my rifles and it seems to work. No real accuracy problems and the barrel Chanel spacing seems to be rather even. I have three Weatherby Mark V's, two synthetic stocked and the other very nice piece of Deluxe wood. I have tightened the guard screws wrong I guess, but the shot groups and barrel Chanel spacings seem to like what I did. Is this a recommendation from Weatherby?
The same question was asked in 2016, because between 1975 and 2009 the owners manual published the front screw sequence for the action screw torque, and from 2010 to present the tighten the rear screw sequence for torquing the action screws was published. The following is the official response that I got from Weatherby's Scott Morrell who was the director of Service and Maintenance at the time.
Thanks for bringing this thread to our attention:
The older method of torquing basically presented issues (especially when the stock has an aluminum bedding block). The problems we see are the result of applying too much torque to the front screw and then torquing down the rear. This can actually cause the receiver to flex, which is not good. That doesn't happen with wood stocks torqued to 35 in/lbs, like those used in the past. That being said..
We've found the current method, as listed in the Vanguard Series 2 manual, is the proper way to tighten down action screws. This method lends itself to the best accuracy, and it cuts down on the possibility of damage to the firearm's components if improperly assembled or if the action screws are over-torqued. If a customer has an older gun, then they should follow the current method and sequence for torquing the action screws.
Current sequence for Vanguards:
1) Insert the trigger guard assembly with its follower and spring into the stock and hold in place.
2) Insert the trigger guard screws and, with a screw driver of proper size, lightly seat the screws while holding the rifle in a vertical position with the butt down. Pull down on the barrel to help seat the recoil lug on the receiver with the mating surface in the stock.
3) Tighten the trigger guard screws to the proper torque and in the proper sequence as follows. Always tighten the rear screw first to a torque of 35 inch pounds, followed by a torque of 35 inch pounds to the front screw. For wood and synthetic stocks this is the final torque value that should be used. On composite stocks with aluminum bedding blocks, apply additional torque to 55 inch pounds to the rear screw followed by 55 inch pounds to the front screw.
I hope this helps.
