"Applied Ballistics for Long-Range Shooting" book by Litz is a good reference for this and many of the other factors related to long-range shooting; it contains test results for a large number of bullets, and includes his ballistics software program. Instead of the traditional G1 BC, a significant focus is on using G7 BC which is based upon comparison to the current streamlined bullets. Cost is around $55 and I think well worth it as it discusses a wide-range of topics in a semi-technical manner to help you better understand what is really going on with the bullet flight.
