Overview
Muzzle energy is the kinetic energy of a projectile (bullet, pellet, etc.) as it leaves the muzzle of a firearm. It is a critical measure of potential stopping power and terminal ballistics.
💡
Pro Tips
Always verify the projectile weight as listed by the manufacturer.
Velocity can be measured using a chronograph at the muzzle.
Higher muzzle energy doesn't always mean better effective range, as aerodynamics (BC) play a huge role later in flight.

Fun Facts
"The energy of a typical .22 LR bullet is about 130-150 ft-lb."
"A .30-06 Springfield hunting rifle can produce over 2,800 ft-lb of energy."
"Air resistance starts decreasing energy as soon as the bullet leaves the barrel."
