Stellate-shaped exit wounds, which in rifle wounds occur over soft tissue as well as over bony surfaces, are common and may resemble contact entrance wounds. Beveling is caused by the forward moving force of the bullet, which creates a cone-shaped deformity as it pushes through the layers of bone. Exit Wounds. Exit wounds - as we have already mentioned - are usually larger than the entrance wound and this is because as the round moves through the body of the victim it slows down and explodes within the tissue and surrounding muscle. Initial gunshot wound care involves stopping bleeding and keeping the wound as clean as possible until doctors can evaluate the situation. Call 9-1-1 for emergency medical assistance. Give first aid for gunshot wounds. Apply direct pressure to the site, if possible, to control bleeding. Gunshot wound. Male skull showing bullet exit wound on parietal bone, 1950s. A gunshot wound (GSW) is physical trauma caused by a bullet from a firearm. Damage may include bleeding, broken bones, organ damage, infection of the wound, or loss of the ability to move part of the body. A contact wound is one in which the muzzle of the weapon is held against the body at the time of discharge. Subsequent autopsy will reveal soot and unburnt powder particles in the wound track.

An exit wound differs greatly from an entrance wound. An entrance wound is surrounded by a reddish-brown area of abraded skin, known as the abrasion ring, and small amounts of blood escape through. An exit wound, on the other hand, is larger and more irregular, with extruding tissue and no abrasion ring.

In general, a straight through bullet wound that does not hit major organs, blood vessels or bone, tend to cause less damage. If a bullet remains inside, it is likely to need removal, causing further damage. Note also that the bullet is likely to have fragmented, requiring searching for the fragments and removing them.

Stippling is the unburned gunpowder imbedding into the skin around a wound. Pseudo stippling is punctate abrasions produced by objects other than gunpowder.

A bullet that passes through the body (creating an exit wound) generally will cause less damage than one which stays in the body, because a bullet that stays in the body transfers all of its kinetic energy (and ensures maximum damage to tissue). This is the aim of most modern ballistic design.

A non-expanding (or full-metal-jacket) bullet often enters the body in a straight line. Like a knife, it damages the organs and tissues directly in its path, and then it either exits the body or, if it is traveling at a slower velocity, is stopped by bone, tissue or skin.

The factors that can affect the amount and distribution of gunshot residue (GSR) on skin and clothing include: (1) firing distance, (2) length and diameter of the firearm barrel, (3) characteristics of the gunpowder, (4) angle between the firearm barrel and target, (5) characteristics of the cartridge, (6) the

https://en.wikipedia.org/wiki/Penetrating_trauma

An injury in which an object enters the body or a structure and passes all the way through is called a perforating injury, while penetrating trauma implies that the object does not pass through. Perforating trauma is associated with an entrance wound and an often larger exit wound.

A shored exit wound is one in which the skin is in contact with another object when the bullet exits; this causes an irregular area of abrasion on the skin, which can be confused with the abrasion ring of an entrance wound.

The bullets don't enter the body cleanly — they ricochet, fragment, and expand inside the body, which destroys the tissue it touches and the surrounding area. If you survive a gunshot wound, this means you may face paralysis from spinal damage, colostomy bags from intestinal perforations, or amputation from infection.

Gunshots wounds that pass through the body without hitting major organs, blood vessels, or bone tend to cause less damage. You may have bullet pieces that remain in your body. Often these cannot be removed without causing more damage.

It's a very 'hot' pain. It feels the way a very flushed face or a blister feels, but intense and painful. After a little time passes, the area around it has this very unexpected achy pain that feels more like what you would expect from being hit with a bat than being shot.

The main cause of death at the scene is usually blood loss — if a bullet damages key blood vessels and there is not enough time to stop the bleeding, the victim will bleed to death or form a rapidly expanding blood clot that critically compresses important brain tissue.
