MV = 2710
G7 BC = 0.419
DC = 0.870
Yields:
0.0 moa @ -> 300 yds
10.9 moa @->700yds
22.55 moa @ 1042yds
34.6 moa @->1342yds
That's the best I could do to model the trajectory provided in the initial Post, using the provided atmospheric conditions with coriolis and spin drift turned on. That MV is likely low, and the DC has been modified quite a bit which raises the red flag. This is a bit like a dog chasing its tail, and is why I prefer nailing down the MV. We're guessing on both the MV and the DC/BC in order to build a LB predicted trajectory to match the measured trajectory at these four yardages.
If I use the revised Berger G7 BC = 0.419 and a DC = 0.500, I can't closely match the drops/trajectory no matter which MV I use. The 1042 yd POI seems to require a higher BC than the 0.419 in order to match with the 700 and 1342yd POIs. The best MV match using a G7 BC = 0.419 and a DC = 0.500 is approximately 2742 fps.
Chronograph that puppy!
