Hornady Enhances 4DOF Ballistic Calculator
Grand Island, NE – Introduced in August 2016, the new 4DOF™ (4 Degrees of Freedom) Ballistic Calculator has become a popular resource for those seeking more accurate trajectories, especially at extreme ranges. Calculations with the Hornady® 4DOF™ calculator now include earth based effects, zero angle, range units and temperature sensitivity factors.
The 4DOF™ calculator provides trajectory solutions based on projectile Drag Coefficient (not ballistic coefficient) along with the exact physical modelling of the projectile and its mass and aerodynamic properties. Additionally, it is the first publically available program that correctly calculates the vertical shift a bullet experiences as it encounters a crosswind; referred to as aerodynamic jump. The use of drag coefficients, correct projectile dynamics, aerodynamic jump and spin drift enable the Hornady 4DOF™ ballistic calculator to be the most accurate commercially available trajectory program.
