[QUOTE="RockyMtnMT, post: 2672076, member: 7999"] I believe this is correct. We have been doing long range testing sessions with multiple rifles shooting multiple diff bullets, for years now. Inevitably I wind up hold nearly identical wind for each rifle. This never has made sense to me, but always chalked it up to, oh well, and let it go. I think it has much more to do with time of flight and mass. A higher bc bullet fired next to a lower bc bullet with the same weight and vel will net the higher bc bullet less drift due to time of flight. Two bullets of the same bc and vel but one heavier will net the lighter bullet with more drift. bc is accurate at predicting drop, to a point. bc has been used as a predictor of drift, and marketed as such, when it is not. bc is an indicator of drift, at best.
