I am SOOOOOO confused. HEEEEEEEELP!!!!!!!!!!!!!!!!!!!!!!

Input Data
Near Velocity: 3100.0 ft/sec
Flight Time: 0.200000 sec
Distance: 600.000 feet
Temperature: 26.0 °F
Barometric Pressure: 29.60 in Hg
Relative Humidity: 77.00 %
Altitude: 88.0 feet
Air Density: 105 % of Sea Level

Output Data
G7 Ballistic Coefficient: 0.510
Far Velocity: 2903.1 ft/sec

Heres the adjusted BC .510 when entered into the G7 trajectory the drop at 600 yards is still 38.3 nothing changed. So even a adjusted BC did nothing. Now I could be doing all this wrong and if I am please correct me with the JBM ballsitic software.
And I conceed to Mike that he was correct and not I as well as you were Jerry and thanks for helping me understand that.
Heres the data using a G1
BC (Time) Output
Input Data
Near Velocity: 3100.0 ft/sec
Flight Time: 0.200000 sec
Distance: 600.000 feet
Temperature: 26.0 °F
Barometric Pressure: 29.60 in Hg
Relative Humidity: 77.00 %
Altitude: 88.0 feet
Air Density: 105 % of Sea Level

Output Data
G1 Ballistic Coefficient: 1.057
Far Velocity: 2903.7 ft/sec
I guessed pretty closly to 1.057 with 1.05. But we all know that this number is impossible for a bullet like this with a G1 function (right)?

Maybe your measurement method doesn't get you there. IAW, if you shoot 600yds at a big enough target, I think you'll find that the bullet is hitting ~47" below the bullseye.
I'm pretty sure that holdover doesn't correlate well with actual bullet path(JBM's "drop").
