通过对国产64式手枪的射击实验,从新枪发射子弹开始,其发射子弹的数量不断增加,当射击次数的增多使得到枪支机件轻度、中等、严重等不同程度的老化。对其射击的弹壳上各种射击痕迹的不断具体变化特点进行分析,研究了不同阶段64式手枪射击弹壳上痕迹的同一认定检验价值,为64式手枪射击弹壳的检验鉴定工作提供了客观的依据。 Through shooting experiments on domestic 64 pistols, the number of launching bullets started to increase from the time a new gun fired its bullets. When the number of shots increases, the number of shots causes mild, moderate and severe degrees of aging to some extent. This paper analyzes the continuous changing characteristics of various shot marks on shot shells, and studies the same test value of the marks on the shotguns of 64 type shot pistols at different stages, which provides an objective basis for the inspection and appraisal of 64 shot pistol shot shells .
