Where did you find this all i could find was for the G1 on there web page????????? But i came up with a BC of .768 for above 2300fps

Bryan Litz, a member here, told me from research he did . he wrote a book, Book Review - Applied Ballistics For Long Range Shooting you should check it out. it is on the main page, there is a review of it, he also has a ballistics program and pointed me to some very good formulas for other calculations also.
