ABOUT THE INFLUENCE OF A SHOOTER ON ACCURATE SHOOTING FROM SNIPER WEAPONS
This article discusses the causes that lead to an inaccurate shot, namely, those related to the shooter: hand tremors, perception of recoil momentum and trigger handling techniques. For comparative analysis, hand tremor and the perception of recoil momentum were chosen as the causes that lead to the greatest deviations of the weapon from the aiming point. Movements of small arms that occur in the "shooter-weapon" system due to the natural tremor of the shooter's hands are determined using a kinematic calculation based on experimental data from open sources. With the help of a system of differential equations, which includes the equations of the rotational motion of a solid body and the equations of gunpowder combustion in a thermodynamic setting, the effect of recoil on the shooter during a shot is described. For weapons chambered for .338 Lapua Magnum and with mass-dimensional characteristics similar to those of the SV-338 rifle, a numerical assessment was made of the values of additional throwing angles that arise due to the indicated reasons at the moment the bullet leaves the bore and lead to additional dispersion of bullets. The maximum values of additional scattering are estimated.
