Re: BCs and time of flight
Dar, take your same example of heavy vs light and compare the Litz BCs of the Berger 155.5 Fullbore bullet and the 208g Amax. I did the calcs on the Berger starting at 2950 fps and the Amax at 2500 fps.
Elevation MOA from 100 yard zero with 155.5g 600 yards to 1000 yards:
12.4, 16.1, 20.4, 25.2, 30.7
Elevation for 208 Amax
16.3, 20.7, 25.5, 30.9, 36.8
Wind drift for 155.5, 10mph cross wind at 3 oclock:
4.4, 5.4, 6.5, 7.6, 8.9
Wind drift for 208g Amax:
3.9, 4.7, 5.6, 6.5, 7.5
I worry about wind drift, so if I could tolerate the recoil, I would rather shoot the Amax over the Berger.
