Question for you and what you are using, if you already know how fast your bullet FPS is, why does every app that I know of ONLY adjust FPS and not BC? AB gives you their hidden BC which according to them is the perfect BC adjust FPS! I know how fast my bullet is! Eagle ballistic to my knowledge is the only app that tunes your BC. Also gives you the tool in your phone to measure scope height. Has scope correction. I can keep going.Shooter!
With all the money and time we all spend on trying to get better at what we do and those once in a life time shots or just making your buddy cry because you hit everything on the range he couldn't on the first shot. BUY THE MAN"S APP and stop wasting your money on the other stuff I promise you will be happy!
