I think you may be confused by all the recent hype about long range "hunting".
May I suggest that you concentrate on learning how to hunt, which is way more complicated than just shooting accurately.
Skilled hunters stalk as close as possible. And they use bullets designed for hunting. Target shooters are justifiably proud of long range shots, and use the most accurate bullet available to consistently shoot tiny groups. Both pursuits have their experts, and some individuals are both competent hunters and precision target shooters, but the overlap is not as common as one might believe.
Hunters are proud of placing a shot as accurately as possible under various difficult field conditions, which means getting as close as possible as the first priority. Hunters next priority is to use a bullet that is designed to penetrate adequately and expand reliably while holding together at all velocities ( = distances) that a reasonable shot may be taken at. Ultimate accuracy is never the real hunter's primary goal, unless hunting for tiny varmints. Far too many big game animals suffer and die wasted by people who are duped by the marketing hype about long range "hunting".
To answer your question, the best hunting bullet for your Ruger 30-06 is the bullet that performs the best INSIDE THE GAME YOU INTEND TO SHOOT and that YOU can shoot into a 6" or smaller group at the range that you intend to shoot it at. Nosler partitions, Barnes "x" bullets, and core bonded bullets are worthy of consideration for hunting big critters like moose and elk. Standard hunting style soft points are good for smaller "big" game. Target bullets should stay on the range, not in the bush.
