The author performed a numerical calculation based on the statistical modeling method of the average impulse transmitted by protons to the projectile body in the railgun channel. The author carried out the analysis of the data obtained and the estimation of the optimal proton energy in the plasma formation for the maximum transfer of momentum in the motion direction to the projectile in the railgun channel. The optimal energy in accordance with the results obtained is in the range 66 ... 67 eV. Acceleration of plasma protons in the railgun channel to a speed corresponding to the found optimal proton energy will increase the efficiency of railguns, which curently does not exceed 40% in experimental facilities.
