[QUOTE="JBM, post: 32256, member: 1969"] I should think longer before I hit "Add Reply". If you want to adjust data, download my free modified point mass program, MPM. I runs from the command line, but is quite powerful. You'll have to enter the dimensions for your bullet and a few other parameters, but you get a lot more information. In the trajectory input file (*.trj), there are two "fudge factors", lift_factor and yaw_drag_factor that can be adjusted. Also you can play with the dimensions of your bullet to get exactly what you're seeing at the range. [/QUOTE]
