Unlike handguns and rifles which have lands-and-grooves cut on the inside of their barrels, shotguns have a smooth bore. Lands-and-grooves cause specific identifying features (rifling) on projectiles as they pass along the barrel. These markings allow examiners to test-fire weapons and compare test-fired bullets to those discovered in bodies. Since shotguns have no lands-and-grooves, their projectiles cannot be positively matched to those found at the scene or inside a body.

A shotgun cartridge contains pellets, gunpowder electricity outage sacramento, and a wad that separates the pellets from the gunpowder. Some ammunition have plastic shot containers that hold the pellets and also act as the wad. The recovery of the wad or plastic shot container is important because they may be specific for certain types of ammunition. Shotguns usually fire pellets; however, slugs can also be used as ammunition.

The range (distance) of fire can usually be more easily determined in shotguns than in handguns or rifles. In addition to the presence or absence of gunpowder, the presence or absence of pellet spread aids in the distance determination electricity 4th grade powerpoint. However, it is still important to test-fire the same gun and ammunition that was used in the shooting to determine an accurate comparison with the distance in question. figure 8.1 A shotgun blast can be very destructive. This man stuck the gun in his mouth. figure 8.2 Tight contact shotgun wound of the chest. All of the gunpowder is inside the wound. The wound edges are abraded and there is a thin linear abrasion on the upper right from the muzzle. figure 8.3 Loose contact shotgun wound and a larger, more ragged exit wound. figure 8.5 This loose contact suicide wound to the neck is larger than expected because the neck was t gasthuys bent over the barrel. Most of the decedent’s face was blown out. figure 8.7 Pellet spread may be used to aid in distance determination when there is no more gunpowder. In this case, the pellets are beginning to spread. Once again, the distance may be determined with accuracy only if the same ammunition and weapon are test-fired. figure 8.4 Loose contact shotgun wound to the back of the head and neck. The decedent was essentially executed during a robbery. figure 8.6 This cookie cutter type wound shows a few separate pellet injuries forming as the distance increases. This is not a suicide. figure 8.8 The central defect may be small as the weapon is moved further away from the shell gas credit card 5 body when fired. The wad was discovered in the body.

figure 8.9 The spread of pellets indicates a considerable distance; however, the distance is affected by the choke of the weapon. Adjacent to the corner of the mouth is an abrasion from the gas density wad. figure 8.11 This woman was shot with a shotgun. The wound does not appear like a typical shotgun wound. Many of the ragged defects were not caused by pellets. See next photo. figure 8.12 An X-ray revealed multiple pellets and other odd-shaped metallic objects. These other objects were keys and the ring they were on. The woman was wearing a ring of keys around her neck. The white arrow points to a zipper. She was X-rayed in a body bag. figure 8.13 This man had two shotgun wounds. The lower one in the abdomen reveals a pellet direction up to the decedent’s left.

See next photo. figure 8.20 Fragments of bone caused damage to the right upper arm. See next photo. figure 8.21 Fragments of bone from her knee were imbedded in her face (arrow). This gives an indication of her defensive grade 6 electricity experiments posturing at the time of the shot. See next photo. figure 8.22 This is her right arm where the second shot began. This wound is superficial. There is gunpowder on the inferior aspect (to the right). See next photo. figure 8.23 The main charge from the second shot entered the left side of the chest, creating this huge defect. There were a few small exit wounds on the gasbuddy left back.
