Abstract: An improved method for dialing in the required number of revolutions of adjustment on a riflescope elevation knob to compensate for bullet trajectory. An elevation knob having the computed yardage increments marked at the calculated point of rotation begins along the bottom edge of the knob and winds completely around the knob in a series of ascending rows with each yardage increment, having a vertical line of reference leading down to the bottom edge and reference point on the knob. The required revolutions of adjustment are made by rotating the knob from an inputted yardage increment and either passing all consecutive increasing increments for a larger increment setting or passing all consecutive decreasing increments for a smaller increment setting. The elevation knob stem mount on a riflescope is calibrated to match each corresponding revolution of the Tuned Trajectory Compensator knob.
