I have found it to be a non issue. Both the bolt and action are cut on cnc equipment. Under the pressure of firing I believe the 9 lugs in 3 rows act essentially like a 3 lug Bat, Sako TRG, Browning A Bolt, TC Icon, Barnard. This is a much more stable arraignment than a 2 lug configuration. Ever sit on a two legged stool? They need addition support or you are going over. How about a 3 legged stool. Damn, it is just naturally really stable. The stability of the tri-pod arraignment is undeniable.
With the extra clearance the bolt body has in the Weatherby just like any two lug action, will look like they are not touching evenly due to being jacked up by the sear. When lapped with the bolt stripped and the trigger removed they actually touch pretty well. So lets say the bolt lugs were just filed on there by hand. It's still in a 3 leg arraignment and as long as any one lug on that plane is touching, the bolt face is going to remain stable. It matters zip if one or two lugs isn't making as much contact as the others. That fact that a Weatherby is 3 rows of 3 just make it that much more stable. Kind of like a rough cannon breech that has lots of rows of lock lugs. Do you remember the accuracy of these things had?
Back to the Weatherby. I check every one and have yet to find one that really needed anything as far as truing up. I had the same conversation with Krieger as they were involved in some custom work with Weatherby a few years ago and he stated the same thing. You can go through the motions and when you start cutting the action face and bolt face were right there square wise.
I think it's a great design.
