[QUOTE="damoncali, post: 504918, member: 33016"] I've called Bryan's book "revolutionary" before. Because it's high time the shooting sports industry get with the program and accept that for almost all long range bullets, the G7 is the way to go, and that the average shooter is not too dumb to know the difference between G1 and G7. That said, there are some bullets for which G1 is better. If it's flat based and blunt, G1 is likely to be a better fit than G7. To bring home the point, I wrote a ballistics calculator using Bryan's data (sadly, only from the first edition - I don't have a copy of the 2nd yet). (You can find it at [URL="http://bisonballistics.com/point_mass_calculations/new"]Bison Ballistics Calculator[/URL] - it's free for all to use). I've set it up to automatically choose the best drag function. (Almost all are G7, but I think that says more about the bullets Bryan selected than the overall superiority of G7 in general). So no, you're right on. It's time for a long overdue change. Best tool for the job and all that. [/QUOTE]
