[QUOTE="7mmTikkaShooter, post: 2591288, member: 92915"] You’re setting up your calculator with 10 mph target speed. Unless you’re actually shooting a moving target, you should set that value to 0. The program is trying to incorporate how much drop is needed to hit the target at specified ranges based on flight time of the bullet. Simply put, a target at 300 yards but moving at 10 mph will actually be farther away by the time the bullet arrives. Think Pythagorean theorem and that’ll help understand. The longer the distance, the longer the flight time which equals more drop calculated. Unless you know the wind speed and direction for the day you shoot id recommend setting that value to 0 as well, at least for validation purposes. Try that and see if your numbers get closer.
