I can imagine this to be a more of a serious problem with the 50-100's etc. firing 650+ grain bullets.

The barrel torque or twisting can be controlled by holding the butt of the rifle as shown in the post below.
The torquing is created by the heavy bullet as it passes through the rifling at high speed, becoming engraved and rotating.
Holding the rifle by the butt also helps to protect the shoulder from felt recoil.
