The following table shows the value of the shot flight speed (m/s) at different distances for cylindrical shafts with an initial emission rate of 375 m/s
(Handbook of the hunter Under the editorship of M. S. Dolbik)
Gunpowder "Sokol" gives the normal weight of the charge of shot initial speed of approximately 375-400 m/s. The shotun should ensure the defeat of the game 4-5 pellets of the respective rooms. Speed of shot at the moment of defeat should be not less than 190-200 m/s
