In the article the estimation of exactness of determination of change initial velocity of shell is resulted at the different methods of its adduction and normalization. Analytical dependences of estimation of exactness of methods of adduction and normalization of measuring of initial velocity of flight of shell are offered, which allow to conduct the calculations of middle errors of these methods at determination of options for firing of complete preparation a method. The results of calculations of middle error of rejection of initial velocity and total rejection of initial velocity of flight of shell are resulted at the different methods of its adduction and normalization for 152-мм SG 2С3М and 122-мм г of D-30.
