My only complaint with my vintage Mark V was that the beautiful wood stock would walk every couple of years. I sent it back to Weatherby twice. They would return the accuracy, but the stock would eventually move again.
I swore off Weatherby rifles and wood stocks and didn't look back for many years. It wasn't until luminant wood stocks came into play that I considered wood again.
Yup,,. Warping Wood, WAS a Big issue, in the Old days ! ( NOT just for, Weatherby's, either ! )
My 1st, Mk-5 Weatherby, in .270 Wby was, a Barreled action that, I bought off, a Widowed Lady then,..
bought, a Reinhart Fajen, Circassian Walnut Stock and AcraGlass bedded, the Action and Barrel Channel that, I channeled Out in, a Pyramid shape with, Holes drilled every 2 inches for MORE Glass Bedding "Support".
A few Pounds of, Up-ward "Thrust" on the Bottom of, the Barrel "Locked" it in for, repeatable Good, Accuracy,..
After, the Glass "Set up" !
In the 1970's and 1980's, I Glass Bedded, at least, a couple Hundred, Wood Stocked, Rifles.
Mounting Scopes, Trigger Tuning, Recoil Pad installs and Glass Bedding, WAS my "Bread and Butter" weekly, Work
