Muzzle Velocity Calculator

Formula

The formula to calculate the Muzzle Velocity (V) is:

$V = \sqrt{\frac{2 \times KE}{\frac{M}{7000}}}$

Where:

$V$ is the muzzle velocity (ft/s)
$KE$ is the muzzle energy (lbf-foot)
$M$ is the mass of the bullet (grains)

What is a Muzzle Velocity?

Muzzle velocity is a measure of the total speed of a bullet as it leaves the muzzle of a firearm after being fired. It is a crucial factor in ballistics, affecting the bullet's trajectory, impact, and overall performance. Higher muzzle velocities generally result in flatter trajectories and greater impact energy.

Example Calculation

Let's assume the following values:

Muzzle Energy (KE) = 1200 lbf-foot
Mass of the Bullet (M) = 150 grains

Using the formula to calculate the Muzzle Velocity:

$V = \sqrt{\frac{2 \times 1200}{\frac{150}{7000}}} = \sqrt{\frac{2400}{0.0214286}} \approx \sqrt{112000} \approx 334.66 \text{ ft/s}$

The Muzzle Velocity is approximately 334.66 ft/s.
