For deer, you are wasting your $ if you purchase premium ammo. Remington corelokts and winchester powerpoints will kill deer just as fast, and are much cheaper.

I personally prefer 150 gr for whitetail. You're gonna get an exit wound with a 30-06 99.9% of the time, regardless of bullet weight.

150 gr will recoil less, and the extra velocity will give you flatter trajectory and more shock.

I shoot 150 gr corelokts in my 30-06 and 150 gr powerpoints in my 308.

good luck
