Box o truth did testing on bullet deflection. They setup a target 10 yards in front of another target. The first target was shooting through 1" dowels then they measured deflection at the second target. They then shot 5 or 6 different rounds through it and found the heaviest rounds did the best. .223 did the worst although the was only 4" of deflection. Not enough to miss a deer. 308 and larger showed almost zero deflection through the 1" dowels.
Although they didn't test 30.06, I would assume it would do as good or better than the 308.
