[QUOTE="BryanLitz, post: 268598, member: 7848"] FWIW, I measured the G1 BC of the 208 Amax to be 0.633 (average value from 3000 to 1500 fps) and the G7 BC is 0.324 (valid for all speeds). Using this BC, you're velocity would have to come down from 2950 to match your trajectory. You asked about a more 'methodical' way. The first step is to measure your muzzle velocity. You can expect about 5" of spin drift with the 208 Amax at 900 yards from a 1:10" twist barrel. -Bryan [/QUOTE]
