if your shots are no greater than 350 yards, and less than 500 for that matter, I don't think going with a heavy high BC bullet really offers anything for you at those ranges. I would recommend going the other way, slower twist and ligther bullets, use the higher speeds they offer to obtain a flatter shooting combo.
heavy high BC bullets don't shine until you get beyond 500 yards, and at that range you need to start looking at vertical spread and a host of issues, with most being load development and the accuracy your rifle is capable of. the action you wanna use is not conducive to this sort of pure accuracy, it would be like putting a porsche engine in a chevy pickup truck.
an 85 grain game king autta do what you want, pushed as hard as you can get it.
