I believe the onus is on the hunter to understand the terminal performance on game, and let this dictate his conditions of use. Relevant to the 6.5PRC/6.5x284 class cartridges, generally, the heavy, high BC bullets do not deliver the level of wind drift benefit you state, at least at hunting distances. The velocity loss due to the heavier bullet offsets the improved BC. The major advantage given the bullet has has good expansion characteristics is increased terminal energy. I have found this to be the case with a recent load development of the Berger 156 Elite Hunter. compared to the 140hVLD. With optimized loads, trajectory and wind drift are close to identical, but 1000 yard energy is 15-20% greater.
Compare apples To apples. The Berger only has a bc if .678 while the heavier of the two atips has a bc of .704 The atip is going to retain an even better bc over the berger at 1000 yds where the velocity's of both bullets will be around 1700fps. Do the math.
