Probably the bedding isn't right. Not if it is factory original. They (some Wby's at least) are not bedded FLAT, but bent into shooting position by the action screws. Bad way of doing things.
If you don't want to modify the factory stock, you need to buy a torque wrench and torque the action screws
!. to factory specs, then
2. play around with them to find the sweet spots if you need to.
Or: rip out the factory bedding and bed it properly.
I did this to a friend's rifle here in Kotzebue. It went from 5 inch groups (screws tightened snug without torque wrench) to MOA or less, no torque wrench needed.
His had an aluminum bedding plate in it, which needed milling out to flat-bed the receiver and barrel properly into the stock, which we did not have access to, so his barrel climbs upward toward the front of the stock, but the SOB shoots!. Which is what he wanted.
Just another good reason to avoid Weatherbys.
What are the other "good" reasons you have to avoid Weatherbys?
