Enter the bullet weight and velocity into the calculator to determine the bullet’s power factor. The power factor is a measure used in competitive shooting to score the momentum of a bullet.

## Bullet Power Factor Formula

The following formula is used to calculate the bullet power factor.

PF = (BW * V) / 1000

Variables:

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

To calculate the bullet power factor, multiply the bullet weight by the velocity and then divide by 1000.

## 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.

## How to Calculate Bullet Power Factor?

The following steps outline how to calculate the Bullet Power Factor.

- First, determine the bullet weight (BW) in grains.
- Next, determine the velocity of the bullet (V) in feet per second.
- Next, gather the formula from above = PF = (BW * V) / 1000.
- Finally, calculate the Bullet Power Factor (PF).
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

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

bullet weight (BW) = 230 grains

velocity (V) = 850 feet per second
