Our ballistics calculator uses proven external ballistics formulas to predict bullet trajectory. The calculations account for muzzle velocity, bullet weight, ballistic coefficient (BC), zero range, and target distance. The calculator uses industry-standard ballistic models to provide accurate predictions for hunting and precision shooting applications.

Understanding Ballistic Coefficient

Ballistic Coefficient (BC) is a measure of a bullet's ability to overcome air resistance. It's calculated based on the bullet's shape, weight, and diameter. Higher BC bullets lose velocity more slowly, resulting in flatter trajectories and less wind drift. BC values are given for different drag models (G1, G7), with G1 being most common for hunting bullets and G7 better for long, boat-tail match bullets.

• Verify muzzle velocity with a chronograph for accuracy
• Use manufacturer-provided BC for your specific bullet
• Account for altitude, temperature, and pressure at shooting location
• Confirm zero at your specified range before using drop data
• BC can vary with velocity (use average BC for range)
• Always verify calculator predictions with actual shooting
