[QUOTE="RockyMtnMT, post: 1090335, member: 7999"] Make sure your scope height is correct. Humidity will also play in there. Muzzle vel is a giant variable. Chronographs give differing information depending on the light at the time of testing. If you are confident in all these inputs then adjust your bc in your program until it matches up with your drops. I have chased chrono reading in circles. Very tiresome. We got a magneto speed. Now I always feel confident in my velocity input, which gives me confidence to change bc to match drops. The given bc value can be influenced by twist, mv, and altitude. The given bc should get you close enough to make your personal adjustments. Steve [/QUOTE]
