[QUOTE="daveosok, post: 79661"] 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.

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.
