Enter your distance to target, caliber, and muzzle velocity into the calculator to determine your bullet drop.

Shooting Calculation Formula

The following formulas are used to calculate bullet drop and adjusted bullet drop based on various factors.

Bullet Drop = (Distance * 0.002) * (Muzzle Velocity / 1000)
Adjusted Bullet Drop = (Windage * 0.1) + (Humidity * 0.05) - (Temperature * 0.02)

Variables:

  • Bullet Drop is the drop of the bullet over a specified distance (inches)
  • Adjusted Bullet Drop accounts for environmental factors affecting the bullet’s trajectory (inches)
  • Distance is the distance to the target (yards)
  • Muzzle Velocity is the speed of the bullet as it leaves the barrel (fps)
  • Windage, Humidity, and Temperature are environmental factors that can affect shooting accuracy

To calculate the bullet drop, multiply the distance by a factor and adjust based on the muzzle velocity. For adjusted bullet drop, consider the effects of windage, humidity, and temperature.

What is Shooting Calculation?

Shooting calculation refers to the process of determining the trajectory and drop of a bullet based on various parameters such as distance, caliber, and environmental conditions. Accurate shooting calculations are essential for precision shooting, hunting, and competitive shooting.

How to Calculate Bullet Drop?

The following steps outline how to calculate bullet drop using the given formulas.

  1. First, determine the distance to the target and the muzzle velocity of your firearm.
  2. Use the formula for bullet drop to calculate the drop over the specified distance.
  3. If using the advanced calculator, input windage, humidity, and temperature to find the adjusted bullet drop.
  4. Finally, check your calculations with the calculator above to ensure accuracy.

Example Problem:

Use the following variables as an example problem to test your knowledge.

Distance to Target = 100 yards

Muzzle Velocity = 3000 fps

Windage = 5 mph

Humidity = 50%

Temperature = 70°F

FAQ

1. What is bullet drop?

Bullet drop is the vertical distance a bullet falls due to gravity as it travels towards the target.

2. How does wind affect shooting?

Wind can push the bullet off course, requiring adjustments in aim to hit the target accurately.

3. Why is humidity important in shooting calculations?

Humidity can affect the density of the air, which in turn can influence the bullet’s trajectory and velocity.

4. Can this calculator be used for different calibers?

Yes, you can adjust the caliber field to match the specifications of your firearm for accurate calculations.

5. Is the calculator accurate?

The calculator provides estimates based on the inputs provided. For precise shooting, it’s best to consult ballistic tables or a professional.
