1. A method of measuring a velocity of a projectile, comprising:
- sensing an acceleration of a firearm in response to a shot being initiated, the sensing being performed with a first sensor being mounted on an exterior of the firearm;
sensing a set of events occurring within the firearm in response to the shot being initiated, the sensing being performed with a second sensor being mounted on the exterior of the firearm; and
calculating a value corresponding to a muzzle velocity of the projectile using the acceleration and the set of events occurring within the firearm.

Abstract
Embodiments of the present technology are directed to systems and methods for measuring projectile muzzle velocity. A muzzle velocity sensor measures an acceleration as well as a set of events occurring within the barrel of the firearm upon a shot being fired. Using the measured data, a muzzle velocity is calculated. The muzzle velocity sensor is used externally to the firearm, requiring no changes to the firearm or the projectile.
