By the way, re. Wby's accuracy guarantees... the old Vanguard was 1.5 in. All of the new models will have a sub-MOA guarantee with factory ammo.
My original Vanguard .257, which began life with the tupperware stock, was sub-MOA out of the box. I installed a Timney trigger and a Fiberguard stock, and it remains one of my all-time favorite rifles.
