How to Use This Calculator

Enter Muzzle Velocity, Ballistic Coefficient (G1), and Range.
Set Wind Speed and Wind Angle.
Review the Wind Deflection result.
Use MOA Hold-Off and MIL Hold-Off to inform your decision.
Use the chart to visualize the results and explore different scenarios by adjusting inputs.

How the result changes with Range

Muzzle Velocity: Bullet muzzle velocity in feet per second.
Ballistic Coefficient (G1): G1 ballistic coefficient.
Range: Distance to target in yards.
Wind Speed: Wind speed in miles per hour.
Wind Angle: Wind angle relative to direction of fire (90° = full crosswind, 0° = headwind).
