Objective In this paper, aiming at the shortcomings of the industry standard of GA/T 1522-2018 Forensic Science Shooting Residue Inspection Scanning Electron Microscopy/X-Ray Spectroscopy, which only provides a few reference characteristic forms and has limited reference such as no reference energy spectrum diagram. Through simulation experiments, a practical reference is provided for the inspection of shooting residues. Methods Taking the shooting of 7.62 mm Type 51 bullet with Type 54 pistol as an example, shooting experiments of naked and clothed human bodies were simulated, and the collection, preparation and inspection steps of shooting residues, typical morphology and composition characteristics of shooting residues were explained in detail. Results Through simulation experiments, the scanning electron microscope morphology and energy spectrum characteristics of the shooting residues produced by the Type 54 pistol shooting the 7.62 mm Type 51 bullet were obtained. Conclusion Each gun and bullet combination has its own specific SEM morphology and energy spectrum characteristics.
