Firearms can be classified as either smooth-bore or rifled-bore weapons. Smooth-bore weapons like shotguns fire multiple projectiles at once, while rifled weapons like pistols and rifles fire a single bullet. Entry wounds vary based on the firearm caliber and distance, from contact wounds with scorching and blackening to distant wounds with scattered powder markings. Exit wounds show a torn hole dependent on the bullet's momentum and any bone fragments carried with it. Forensic analysis of entry and exit wounds can help reconstruct shooting incidents and determine factors like self-infliction, range, direction, and whether a particular weapon was involved.
