** Description:** This article examined two methods of determining muzzle velocity deviation from the tabulated value by promising ballistic station (PBS), which measures the soon-st at the point of extinction nutation oscillation caused a change in initial conditions place the projectile (mines) from the bore guns, described the mathematical apparatus of the first and second methods is given, of the measured velocity of the projectile (mines), evaluated the accuracy of the total deviation of muzzle velocity (mines).

Keywords:
