BulletDrop is a simple external ballistics calculator for iOS. It accepts inputs of bullet weight, ballistic coefficient, muzzle velocity, sight height, zero range, wind speed & angle, etc and calculates velocity, energy, flight path, and drift. Output is displayed in selectable increments out to ranges of 100 to 2000 yards. The default is 50 yard increments out to a range of 1000 yards. You can change these selections in Settings.
BulletDrop is intended for reloaders and shooters of all varieties. It gives them an idea what various cartridges and load recipes will do at the range. The information provided is in no way a substitute for actual range time. Get out and shoot!
