FREE Ballistic App with 4DOF®

The Hornady Ballistic Calculator App includes the advanced 4DOF® calculator as well as a standard BC calculator. Providing more accurate trajectory solutions, the 4DOF® calculator incorporates the projectile's movement in the standard 3 degrees but also adds its movement about its center of gravity and subsequent angle relative to its line of flight, which is the fourth degree of freedom.

Features:

  • Calculates more accurate trajectories, especially at extreme ranges
  • Can be used without wireless connectivity
  • Pre-populated with long range match and hunting style bullets
