I would like to purchase a CD that contains ballistic information for .22s, .20s and .17s,including ballistic coefficients, velocities at 100, 200, 300, 400, 500 yards, trajectories with various bullet weights and different powder loads. I know I may be peeing into the wind on this one, but if there is such information available, I sure would like to see it. Any help would be much appreciated.
