Gunshot residue related studies have become imperative for Forensic Ballistic experts nowadays. It is often a challenge for these experts to determine the distance between a firearm and the target. This determination requires test firing from the firearm at various distances to compare the GSR patterns formed during the test with those observed on the victim or target. The study emphasizes on the distribution of GSR particles deposited on the trajectory at different distances (0 to 8.5 m). AK-47 and SLR weapons were used for the purpose and the results showed that there is a significant difference in the distribution of elements such as sulfur, barium and lead of GSR when analyzed using EDXRF. The study helped us to co-relate the shooting distances with the distribution of GSR.
