I agree that certain bullets are better for certain jobs, but I think people concentrate way too hard on picking that perfect bullet. My great grandfather, grandfather, uncles, cousins, and I have been using regular old soft point lead core bullets for years and years, and have never had any problems killing elk or moose. My dad shoots a 30-06 with 150gr Remington core-lokt bullets as he has for years, and several of my uncles shoot 270's with 140gr core-lokt bullets as they have for years. I now use 150gr Sierra Gameking bullets in my 7mm mag. None of us has ever had any problems killing elk, and we can break their shoulders just as easily as anyone else out there. I shot 160gr Nosler Partitions one season, and cannot tell any difference between them and the 150gr boat tails I'm shooting now other than the fact that my 150's shoot faster and flatter. Unless you're shooting light, explode on impact nosler ballistic tips or heavy bullets that barely expand like failsafes, I don't think you're going to notice much of a difference in performance.
