Ballistics

The examination of standard and country-made firearms, lethal weapons like revolvers, pistols, assault rifles, carbines and ammunition is carried out in this division. The examination of firearms in possession under arms act is also carried out in this division. This division also undertakes the work for examination of gun-shot residues from fired ammunition, shot holes on clothes/skin/ window glasses etc… and distance of firing in cases of murder/assault. For comparing the striations on the fired bullets and firing pin impression on fired cartridge cases from crime scene with test fired bullets and test fire cartridge cases a comparison microscope is used. Integrated Ballistic Identification System (IBIS) is used for preparing a national database of images of markings on cartridge cases and bullets recovered from crime scene. IBIS has integral hardware/software combination designed to compare digital images of bullets and cartridge casings.

Firing Gallery

Ballistics Division having sufficiently long ‘firing gallery’ of 48 x 3 square meters in the premises of FSL, Mumbai, which is helpful in measuring velocity of the bullets, effective range of the weapon, distance of firing in various crime-exhibits and a Sophisticated computerized “Projectile Velocity Measuring System” is being installed in the said firing gallery, which helps in improving quality, accuracy and speed of work .Firing Gallery is also equipped with “Ballistic Gelatin Measurement System”, the camera of this system captures the images of path of bullet in the gelatin block fired from the firearm. This system has specialized software to study the path of bullet and nature of cavities produced by bullet in the gelatin block. The gelatin block simulates the human body. Hence the research work related to human body can be done on these parameters.
