Bullet parts: 1 metal jacket, 2 lead core, 3 steel penetrator. Terminal ballistics is a sub-field of ballistics concerned with the behavior and effects of a projectile when it hits and transfers its energy to a target. This field is usually cited in forensic ballistics.
There was a hole about 0.5 cm from the end of the jacket sleeve [68] and a hole through the back of the doubled French cuff but no exit hole on the palm side. [69] [70] According to the theory, the bullet emerged from the palm side of the wrist and entered the left thigh.
Two shooting victims came in, a man and a woman, about two hours apart, and were quickly patched up. The man was shot twice, in a wrist and a thigh—four holes, not life-threatening. The woman was shot once in the thigh with a small entry wound but no exit wound—a stray bullet that struck her while she was walking down the street.
Before the barrel can release the bullet in a consistent manner, it must grip the bullet in a consistent manner. The part of the barrel between where the bullet exits the cartridge, and engages the rifling, is called the "throat", and the length of the throat is the freebore. In some firearms, the freebore is zero as the act of chambering the ...
A penetration depth of 12.5 to 14 inches (320 to 360 mm) may seem excessive, but a bullet sheds velocity—and crushes a narrower hole—as it penetrates deeper, so the bullet might be crushing a very small amount of tissue (simulating an "ice pick" injury) during its last two or three inches of travel, giving only between 9.5 to 12 inches (240 ...
This bullet derives its name from its popularity for target shooting, because the form factor cuts neat holes in paper targets, making scoring easier and more accurate and because it typically cuts a larger hole than a round nose bullet, a hit centered at the same spot can touch the next smaller ring and therefore score higher.
The bullet's angle of trajectory at the point where it penetrates the skin can influence the shape of the abrasion collar. This can be used by forensic pathologists in discerning an approximate angle of entry and is important in investigations of gunshot wound victims, where evidence of the gunshot's origin is necessary to determine whether the death was homicidal, suicidal, or accidental.
As a result, so-called "bullet-proof" panels may successfully prevent penetration by standard 7.62×39mm bullets containing lead cores, however the same panels may easily be defeated by 7.62×39mm armor-piercing bullets containing hardened steel penetrators. Bullet-resistant materials (also called ballistic materials or, equivalently, anti ...
