New 6.5 Grendel ballistic and charting MOA etc...
#2
You would need to chronograph it to be exact, but can get an idea using a G1 BC of .40 and 2500 fps (reported BC for that bullet and velocity from 16") and plug that and the rest of your info in at JBM

EDIT:
without adjusting for your temp, elevation, air pressure etc. It's pretty close, 2.2" low at 200 and 9.4 minutes low at 430 yards, which would still put you well onto a 16" target with that hold.
