shouldn't need to do any turret twisting to kill a deer at 330 yards with a .270 WSM.
Correct. I shot another at 330 with a 4x Leupold with a 3 minute dot. Placed the bottom of the dot on the back line. Which took care of 4+inches of the approximately 9 inches of drop.
However, 330 or a little more isn’t the game the LR people play. Thus I can see were they may see the need to upgrade their equipment to what gives them an increased confidence level.
