Standard Ballistics Calculator


Our ballistics calculator includes both basic and advanced features, allowing you to customize the shooting conditions to replicate your environment. Choose standard or metric, and enter the appropriate data to view your favorite load.

Standard values are provided in the sight height based on the firearm type, but may be changed to match your setup. Default values are entered in the temperature and pressure spaces but can be changed. Once calculated, we offer a printable "cheat sheet" to tape to your firearm for quick reference.

Input Variables

  • Standard/Metric: Choose the system of measurement you want to use.
  • Description: Use this space to describe the handload or factory ammo you’re using.
  • Ballistic Coefficient: Refer to the trajectory data. (Must be at least .001 up to 1.0)
  • Velocity: Measured in feet per second, or meters per second. (must be between 100 and 4400 fps, or 30 - 1350 m/s)
  • Weight: Bullet weight in grains (must be at least 5 grains up to 300 grains)
  • Maximum Range: The furthest range to which you want to calculate. (from 100 to 1000 yards, or 30 to 1000 meters)
  • Interval: The range interval you want to calculate and display.
  • Drag Function: Use either the G1 or G7 model. This will depend on the bullet you are using.
  • Sight Height: The default is 1.5in/5cm. Can be from .1 to 4 inches/.1 to 10 cm.
  • Shooting Angle: The vertical angle between you and the target. A negative angle indicates you are above the target. A positive angle indicates you are below the target.
  • Zero Range: Defaults to 100 yds/50 meters.
  • Wind Speed: Measured in miles per hour/km per hour.
  • Wind Angle: This indicates the direction of the wind. 0 degrees is a direct headwind. 90 degrees is a crosswind from the right. 180 degrees is a direct tailwind. 270 degrees is a crosswind from the left.
  • Altitude: Your height above sea level.
  • Pressure: Enter the absolute barometric pressure for the shooting site, standard pressure is default.
  • Temperature: Enter in degrees Fahrenheit or Celsius.
  • Humidity: Entered as a percentage.
