Hornady® 4DOF™ Ballistic Calculator


The Hornady® 4DOF™ (Four Degrees Of Freedom) Ballistic Calculator determines trajectory solutions based on projectile Drag Coefficient (not Ballistic Coefficient), combined with exact physical modeling of the projectile and its mass and aerodynamic properties. Additionally, it is the first publicly available calculator that will accurately determine the correct vertical shift a bullet experiences as it encounters a crosswind; referred to as Aerodynamic Jump (AJ).

The Hornady 4DOF also accurately calculates angled shots by accounting for important conditions that current programs overlook. The use of Drag Coefficient and the calculation of Aerodynamic Jump enable the Hornady 4DOF Ballistic Calculator to be the most accurate trajectory calculator commercially available. More...
