So I'm running the Applied Ballistic app on a Samsung Note 4. So I have a Labradar for muzzle velocity. I have created my platform then selected bullet from library. Which Fedeal Match HPBT 168gr. So I enter in a 10 group average 2566.5 and a 6ftps dev. Then in went to trajectory and at zero it starts out wit 2500.5 for the velocity???????
