BALLISTIC CALCULATOR

Calculates downrange velocity V2 at D2 from velocity V1 measured at D1 and the selected ballistic coefficient (BC).

Measured velocity V1 at D1

m/s

Chronograph distance D1 from muzzle

Ballistic coefficient (BC)

lb/in²

Target distance D2 from muzzle

Projectile weight

Sight height

Zero range

“Zero range” is the selected point where the projectile trajectory crosses the line of sight. The calculator sets the bore angle so the projectile intersects the line of sight at the entered range, then finds both crossings: ZERO 1 (near zero) and ZERO 2 (far zero).

A positive value means dial the elevation turret UP; a negative value means dial DOWN. Table values are calculated from the POI and range in each row.
