Using the Ballistics Calculator

This guide will walk you through the process of using the Ballistics Calculator to estimate various ballistic parameters. Ensure you have the necessary information about your ammunition and shooting conditions before you begin.

Step 1: Enter Bullet Information

  • Bullet Weight (grains): Enter the weight of your bullet. The value should be between 1 and 1000 grains, with a precision of 0.1 grains.
  • Muzzle Velocity (fps): Input the muzzle velocity. The acceptable range is from 100 to 5000 feet per second, allowing adjustments of 1 fps.
  • Ballistic Coefficient: Insert the ballistic coefficient for your bullet. Valid entries range from 0.1 to 1.0, with a precision of 0.001.

Step 2: Enter Rifle and Environmental Information

  • Zero Range (yards): Provide the zero range for which your rifle is sighted. This value should be between 25 and 1000 yards, in increments of 25 yards.
  • Sight Height (inches): Enter the height of your rifle’s sights above the bore. This should be between 0.5 and 3.5 inches with a 0.1-inch increment.

Step 3: Enter Environmental Conditions

  • Temperature (°F): Input the environmental temperature, ranging from -20 to 120 degrees Fahrenheit.
  • Wind Speed (mph): Enter the wind speed, which can be anywhere from 0 to 40 mph, with a 0.1 mph precision.
  • Wind Angle: Choose the wind angle from the options provided:
    • Full Value (90°)
    • Half Value (45°)
    • Quarter Value (30°)

Step 4: Calculate Results

After entering all the necessary input fields, trigger the calculation to obtain results. The calculator will compute the following:

  • Muzzle Energy (ft-lbs): This uses the formula (bulletWeight * pow(muzzleVelocity, 2)) / 450240.
  • Bullet Drop at Various Ranges: The calculator will give you the bullet drop in inches at 100, 200, and 300 yards.
  • Wind Drift at Various Ranges: Measure the impact of wind drift in inches at the same ranges (100, 200, and 300 yards).

Conclusion

Review the calculated ballistic data provided by the calculator. Double-check all inputs if results seem unexpected. Adjust your shooting setup based on the insights gained to improve accuracy and precision in the field.
