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, wherein the set of events include at least an activation of a primer of a cartridge within the firearm and a projectile exit from a barrel of the firearm;

    integrating data from the first sensor with data from the second sensor to determine whether the firearm has been fired; and

    calculating a value corresponding to a muzzle velocity of the projectile using the set of events occurring within the firearm.
