Hornady has enhanced the capabilities of its 4 Degree of Freedom Ballistic Calculator, which was originally launched in August 2016. Calculations with the 4DOF 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 modeling of the projectile and its mass and aerodynamic properties. It is the first publicly available program that correctly calculates the vertical shift a bullet experience as it encounters a crosswind; referred to as aerodynamic jump.

The new features include:

• Earth-Based Effects: Accounts for effects due to rotational velocity of earth as well as earth curvature.

• Zero Angle: Accounts for any changes atmospheric conditions can have on your zero range and subsequent trajectory.

• Temperature Sensitivity Factor: Accounts for changes in muzzle velocity with changes in temperature. Features custom input or general table with commonly used long-range powders.

• Range Units: Allows for range units to be output in yards or meters regardless of standard or metric inputs.

"The addition of these new features will help guarantee the most accurate trajectory predictions available," said Jayden Quinlan, Hornady Ballistics Engineer.

The 4DOF Ballistic Calculator is available for free. It can be found here.
