Bullet Power Factor Calculator

Formula

The formula to calculate the bullet power factor is:

\[ PF = \frac{BW \times V}{1000} \]

Where:

\( PF \) is the power factor
\( BW \) is the bullet weight in grains
\( V \) is the velocity of the bullet in feet per second (fps)

What is a Bullet Power Factor?

The bullet power factor is a measure used in competitive shooting to ensure fairness and safety. It is calculated by multiplying the bullet weight by its velocity and dividing by 1000. This calculation gives a number that represents the momentum of the bullet, which is used to classify shooters into different divisions based on the recoil and stopping power of their ammunition.

Example Calculation

Let's assume the following values:

Bullet Weight (BW) = 200 grains
Velocity (V) = 900 fps

Using the formula to calculate the bullet power factor:

\[ PF = \frac{200 \times 900}{1000} = 180 \]

The bullet power factor is 180.
