"The bullet's drop from the muzzle if fired level with the ground would be 85.1 Ft." Don't want to start another whole argument, but the vertical drop of the bullet is dependent ONLY on time-of-flight- which in our example is just about 1.2 seconds, and the gravitational attraction of the Earth (9.8 meters/sec/sec).
Therefore, the vertical drop could not be much more than 35 feet or so- regardless of any other complicating factors.
Unless I have the time-of-flight wrong...
Took the output from the column titled bullet path using a zero range of 5 yards. Shows path of 1022 inches. The more I change zero range inputs this column appears to be calculating path above and below line of sight not drop. So my statement of 85.1 feet is incorrect.
