Abstract

In this article, we demonstrate a method for determination of firing distance based on pellet distribution on targets. This study needs to test firing from the pipegun at various distances viz. 2, 8, 10, 20, 26 ft target to compare gunshot residue and pellets distribution pattern made during the test firing. Smokeless powder particles/gunshot residues (GSRs) on the targets were characterized and analyzed by scanning electron microscopy and energy dispersive X-ray spectroscopy (SEM-EDX). Differences in chemical composition and morphology of GSRs were observed. Gunshot residues were collected from the target by using an adhesive tape. This study revealed that at 2 ft distance blackening and tattooing was seen and after 8 ft distance spreading of lead pellets took place.
