For accuracy, only the rifle's barrel will know. You may have to try a number of different brands to find the factory load that provides adequate accuracy for your needs.
As far as trajectory, there is little difference between a 150, 165, and 180 bullet weight. Deer are a lot different than elk. Deer have light bones, elk have heavy, strong bones. Elk are a lot bigger, so require more penetration to reach the killing zone if the angle is not perfect. A 150 grain bullet is perfect for any deer that walked, a 180 grain bullet is much better for elk. If you shoot your game in the shoulder, a premium 180 bullet would be nice.
