What Does a Bullet SCAR Look Like?
A bullet hole or scar (SCAR) is a common visible sign of a gunshot impact on a surface. Determining the appearance of a bullet SCAR can aid in forensic analysis, legal investigations, and crime scenes. In this article, we will delve into the distinctive features of a bullet SCAR, exploring its typical characteristics, and providing photographs and diagrams to illustrate each point.
Types of Bullet Holes
Prior to examining the appearance of a bullet SCAR, it is essential to acknowledge the different types of holes that can be created:
• Entrance Wound: The hole through which the bullet enters a surface.
• Exit Wound: The hole through which the bullet exits a surface.
• Tumble Hole: Caused by a bullet yawing or tumbling before exiting a surface, producing a larger, irregular entry hole.
• Fouling Hole: Minuscule holes created when a bullet fragments or deteriorates upon impact.
Characteristics of a Bullet SCAR
A typical bullet SCAR exhibits various features, including:
- Shape: Entry holes are usually circular or elliptical, while exit holes can be irregular.
- Size: The size of the entry hole is often smaller than the exit hole, dependent on the bullet’s geometry and velocity.
- Muzzle Blanks: Muzzle blows or muzzle flash can create smudges or residue deposits around the entry hole. These are indicative of near-contact shooting.
- Tumbling: Slight curvature or irregular shapes can indicate a bullet tumbled before exiting.
- Expansion: Hollow-point or expanding bullets leave larger exit holes due to the expansion of the bullet while in flight.
- Burning: Bullet holes can exhibit signs of burning or charring upon impact, particularly with muzzle flash or hot propellants.
- Fracture Lines: Exit holes may display cracking or fracturing of surrounding material, indicating the intensity of the impact.
| Parameter | Typical Variation |
|---|---|
| Shape | Circular/Elliptical (Enter), Irregular (Exit) |
| Size | Smaller (Enter), Larger (Exit) |
| Size (mm) | – |

Factors Affecting Bullet SCAR Appearance
Several factors influence the appearance of a bullet SCAR, including:
• Distance: Proximity affects the size and shape of the hole, with increasing distance resulting in smaller or more irregular holes.
• Bullet Type: Size, shape, and trajectory of the bullet impact vary depending on the type of firearm and ammunition used.
• Surface Material: Penetration, expansion, or fragmentation can be influenced by the surface material, whether it’s wood, steel, or other materials.
