Of the cartridges your asking about my choice would be #1 .308, #2 7mm-08 and #3 .30-30. Even with the new leverevolution bullets improving the 30-30 it would be my last choice. The 308 can handle the 180 gr bullets for bear and 150s for deer. (a 165 gr would be good for both). All 3 are more than capable of taken these critters provided you know their limitations.
