This ballistic calculator tool helps you accurately predict the trajectory of a projectile based on your input parameters.
How to Use the Ballistic Calculator
Enter the following parameters into the calculator:
- Muzzle Velocity: The speed at which the bullet leaves the barrel (feet per second).
- Bullet Weight: The weight of the bullet (grains).
- Ballistic Coefficient: The efficiency of the bullet in overcoming air resistance.
- Zero Range: The distance at which the rifle is zeroed (yards).
- Target Range: The distance to the target (yards).
- Sight Height: The height of the sight above the bore line (inches).
- Wind Speed: The speed of the wind (miles per hour).
- Wind Angle: The angle of the wind relative to the bullet’s path (degrees).
- Temperature: The ambient temperature (Fahrenheit).
- Altitude: The altitude above sea level (feet).
How The Calculator Works
The ballistic calculator uses basic physics and ballistic coefficients to estimate the drop and wind drift of the bullet. The primary factors are:
- Gravity, which affects the bullet’s trajectory causing it to drop over distance.
- Wind speed and direction, which cause the bullet to drift left or right.
- Environmental factors such as temperature and altitude that affect air density and, consequently, the bullet’s flight.
Limitations
This calculator provides an estimation. Actual results can vary due to numerous factors such as bullet design, barrel wear, and exact environmental conditions. It is essential to verify the calculations with actual range testing.
