A shored exit wound in firearms ballistics is characterised by which of the following?

  • A A small, neat, punched-out circular defect with an abrasion collar — identical to the entry wound
  • B A large, stellate, irregular tear caused by re-entry of the bullet after ricochet
  • C An exit wound with a broad, irregular abraded margin due to the skin being supported against a firm surface at the moment of bullet exit
  • D An exit wound occurring when the bullet exits through a joint space with minimal soft tissue support
Correct answer: C. An exit wound with a broad, irregular abraded margin due to the skin being supported against a firm surface at the moment of bullet exit

Explanation

A 'shored' exit wound occurs when the skin over the exit site is firmly supported (pressed) against a hard surface — such as a car seat, floor, or body armour — at the moment the bullet exits. Normally exit wounds are larger, irregular, and stellate without abrasion collar. When 'shored', the resistance of the hard surface behind the skin creates a broad, irregular abraded margin resembling an abrasion collar, sometimes mimicking an entry wound. Identifying a shored exit wound is important in reconstructing the victim's position at the time of shooting.
