During criminal investigation, one may come across cases involving the passage of non-jacketed lead bullets through metal sheets. After these bullets have passed through the sheets, their forensic studies, holes or injuries caused may be of importance. In this paper, the authors have presented the results of passage of lead bullets fired from .32 revolver and .22 rifle through iron sheets of different thicknesses. Studies about their penetration, deformation, diameters of holes caused by them, formation of plug, maintenance of striations left by firearms on these bullets and their lethality etc. have been discussed. These studies revealed that striations left by firearms on their surfaces are maintained, holes caused in thicker sheets are of diameters larger than their calibres and these bullets are capable of penetration into human body.
