Utilize the CWD calculator to determine the necessary adjustments for your shooting accuracy based on various factors such as distance, wind speed, and bullet drop.

CWD Calculation Formula

The following formula is used to calculate the CWD based on the inputs provided.

CWD = (Distance / 100) * (Wind Speed / 10) + Bullet Drop

Variables:

  • CWD is the calculated wind drift (inches)
  • Distance is the distance to the target (yards)
  • Wind Speed is the speed of the wind affecting the bullet’s trajectory (mph)
  • Bullet Drop is the drop of the bullet due to gravity (inches)

To calculate the CWD, input the distance, wind speed, and bullet drop into the calculator above.

What is CWD Calculation?

CWD calculation refers to the process of determining the wind drift of a bullet as it travels towards the target. This calculation is crucial for shooters to ensure accuracy, especially in windy conditions. Understanding how wind affects bullet trajectory can significantly improve shooting performance.

How to Calculate CWD?

The following steps outline how to calculate the CWD using the given formula.

  1. First, determine the distance to the target in yards.
  2. Next, measure the wind speed in miles per hour.
  3. Account for the bullet drop in inches.
  4. Use the formula from above: CWD = (Distance / 100) * (Wind Speed / 10) + Bullet Drop.
  5. Finally, input the values into the calculator to get the CWD result.

Example Problem:

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

Distance = 300 yards

Wind Speed = 10 mph

Bullet Drop = 5 inches
