In this study, we analyze the results of ballistic tests performed on direct fire weapons and propose a method to reduce the number of firing tests for dispersion measurements. In ballistic tests, small dispersion is an important performance indicator of ammunition in direct-fire weapons. The ammunition dispersion test evaluation calculates dispersion via 10 rounds of firing. The same ballistic test is repeated five times, and the average dispersion is calculated to accept the ammunition. Results of the OOmm ballistic test show that most dispersion test results are distributed within a range of 40%-50%. Because OOmm direct-fire weapons are a quality-control system, the ballistic test results are analyzed while assuming a maximum quality change in dispersion of +3 sigma. Simulation results show that the results of the dispersion test can be analyzed using only three ballistic tests. The results of this study can be used as a case study to reduce the number of ballistic tests for the ammunition of direct-fire weapons.
