Ballistics is defined as the study of projectile action, motion, and behavior in any given medium. The projectile travels down the barrel and in the medium towards the main target. In many severe crimes, firearms are the most widely used weapons. Forensic ballistics currently uses analytical techniques in the courtroom to ascertain the use of the suspected weapon in a particular crime and the technical advancement to measure and estimate the range of fire with greater precision along with the possible type of firearm used. The major concern arises in the cases where the firing happens through intermediate targets like clothing. Usually, the Gun Shot Residue (GSR) is present over the wound. Sometimes, the clothing items play a hindrance in the proper evaluation of the caliber of the weapon. The current work demonstrates the effect of 0.22 caliber bullets on different types of clothing using different types of firearms of the same caliber. It also indicates the approximation in the range of firing up to an extent. The main focus was given on the formation of entry and exit holes on different types of clothing material and then the deposition of GSR to study the effect. It was experimentally established that the size of the entry hole varies significantly on different types of clothing material, and the deposition of GSR and scorching pattern also shows noteworthy differences on various clothing materials.
