| Abstract: | Objective To conclude the scattering position of the cartridge case shot by 56 half-motion rifle and find the cartridge case or the firing position. Method Data on the falling point of the cartridge case were obtained and its distribution was assumed and tested. Result The scattering distance and angle of cartridge case was determined correctly. Conclusion The scattering position of the cartridge case was determined so that the cartridge case can be found quickly and the shooting position can be conduded. |
