I have only hunted deer 10 yrs and 9 of them with a 30-30. I always chose 170 grain bullets over 150s because on the charts the larger bullet had more energy at (x) number of yards than the lighter bullet. I asumed that having more energy to transfer = better. So I would have sided with #2 for a different reason, Maybe ignorance. Shot placment being the same, is speed more important than energy?
