Accuracy and bullet placement are far more important than bulet brand, diameter, or weight. My bullet for Montana Mule deer for the past 45 years has been the 117 grain Sierra GamdKing from my .257 Ackley. Before that, I hunted Mule deer with 150 grain Sierra GameKing bullets from my .30-06.
Although I shoot premium bullets in several of my rifles, a standard cup and core 150 to 165 grain hunting bullet from your .30-06, if put in the right place, will kill a mule deer just as dead as any of the new premium bullets.
Choose the bullet that is the most accurate in YOUR rifle!
