MT2000: I have killed all manner of Big Game with my various 30/06 Rifles using the wonderful Nosler 165 grain Partitions!
The game includes Antelope, Blacktailed Deer, Mt. Goat, Mule Deer, Black Bear, Whitetatiled Deer and Elk.
I don't think you can go wrong with the 165 grain Nosler Partitions and well placed shots on any big game from Moose on down to Antelope.
Best of luck to you.
Hold into the wind
