It seems to me, that a 165 or 175 grain bullet with a boat tail form one of the major bullet makers (Sierra, Nosler, Speer, Hornady), would be the logical choice.
Around here, the 165 grain Sierra Gamekings seem to be preferred choice. You have to balance bc, penetration, expansion, bullet integrity and recoil. Recoil depends on how you are physically built, so if you're big you can stand a heavier bullet. The more you focus on bc the more you're going to be led towards hp and that's not good for game.
Experience is a very bad teacher because it first gives you the test and then teaches you the lesson.
