Gunshot residue ( GSR ), also known as cartridge discharge residue ( CDR ), gunfire residue ( GFR ), or firearm discharge residue ( FDR ), consists of all of the particles that are expelled from the muzzle of a gun following the discharge of a bullet. It is principally composed of burnt and unburnt particles from the explosive primer, the ...
Aug 23, 2022 · Gunshot residues (GSR) are routinely exploited by forensic scientists in the investigation of firearm-related events. While many new techniques are daily reported in the literature for the analysis of GSR, there is still a significant lack of data on the transfer, persistence, and prevalence of GSR.
