How to Use the Ballistic Calculator

This guide will walk you through the steps needed to effectively input data and understand the results provided by the Ballistic Calculator.

Step 1: Input Your Data

Begin by gathering the necessary information required for the calculator. You will need to have the following data ready:

  • Bullet Weight: Enter the weight of the bullet in grains. This field is required and should be a number between 1 and 1000, in steps of 0.1.
  • Muzzle Velocity: Provide the muzzle velocity in feet per second (fps). The valid range is between 100 and 5000, with increments of 1 fps.
  • Ballistic Coefficient: Input the ballistic coefficient (BC) for the bullet. It should be a value between 0.1 and 1.0, with a step of 0.001.
  • Zero Range: Specify the zero range in yards, ranging from 25 to 1000 in steps of 25 yards.
  • Sight Height: Fill in the sight height above the bore axis in inches, with acceptable entries from 0.5 to 3.5 inches and steps of 0.1 inches.
  • Temperature: Provide the ambient temperature in degrees Fahrenheit, ranging from -20°F to 120°F in steps of 1°F.
  • Wind Speed: Enter the wind speed in miles per hour (mph). Values should fall between 0 and 40, with steps of 0.1 mph.
  • Wind Direction: Choose the wind direction from the available options:
    • Full Value (90°): 0
    • Quartering (45°): 0.866
    • Half Value (30°): 0.5

Step 2: Submit the Data

Once you have carefully entered all required input fields, submit the data to calculate the results. The calculator will compute various output metrics based on the given inputs.

Step 3: Interpreting the Results

Upon submission, the calculator will provide you with the following results:

  • Bullet Drop: The trajectory calculate show bullet drop at distances of 100, 200, and 300 yards. The values are presented in inches, with two decimal precision.
    • Bullet Drop at 100 yards.
    • Bullet Drop at 200 yards.
    • Bullet Drop at 300 yards.
  • Wind Drift (Windage): Estimated bullet drift due to wind at set yardages. This is again represented in inches, with two decimal points.
    • Wind Drift at 100 yards.
    • Wind Drift at 200 yards.
    • Wind Drift at 300 yards.
  • Velocity Retention: Calculated remaining velocity of the bullet at the mentioned distances in feet per second (fps), rounded to the nearest whole number.
    • Velocity at 100 yards.
    • Velocity at 200 yards.
    • Velocity at 300 yards.

Review each output to understand how the various factors like wind and range impact the bullet’s trajectory and performance. Adjust your shooting plans accordingly based on these insights.
