An apparatus for providing information for adjusting a sight of a projectile weapon is provided. The apparatus comprises an input for receiving information regarding measured velocity of a projectile in flight at least at one moment of time. The apparatus comprises an analyzer for determining the velocity and moment of time; an estimator for estimating value for a set of parameters; a calculator for using velocity, moment of time, estimated value and a zero-in angle of the sight to calculate a velocity of the projectile at the moment of time; and a comparator for comparing calculated velocity and measured velocity to determine whether a difference between the calculated and the measured velocity is less than a predetermined value. The apparatus is configured to repeat estimating, calculation of the velocity of the projectile and comparison with another estimated value for the set of parameters to model a trajectory of the projectile.

G01S 13/72 - Radar-tracking systemsAnalogous systems for two-dimensional tracking, e.g. combination of angle and range tracking, track-while-scan radar
The invention relates to a paintball projectile comprising a front portion and a body portion, which body portion comprises a side wall. The paintball projectile comprises a body component, which is a single piece forming outer surfaces of the front portion and the side wall, a closed cavity in the interior volume of the front portion, a fill in the closed cavity, and a middle component in the interior volume of the body component, the middle component having a first side and a second side. The first side of the middle component is facing the closed cavity, and the projectile further comprises a barrier layer on the second side of the middle component. The invention further relates to a method for manufacturing paintball projectile.
