What Are Rifling Patterns on a Bullet?
When a bullet is fired from a gun, the gun leaves unique markings, or grooves, on the surface of the bullet as it travels through the barrel. These grooves help forensic firearms examiners determine a match between the bullet and gun type and perhaps to the actual gun used in a crime. What is a Rifling Pattern? A spinning bullet is a more accurate bullet. Therefore, many guns have spiral grooves carved into the inside of their barrels to make the bullets spin as they leave the gun barrel. The procedure for carving grooves into the barrel of a gun is called rifling. Cutting the grooves leaves high parts, or lands, intact between them. The grooves grab the bullet as it traverses the barrel and cause it to spin and thereby increasing its accuracy of hitting the intended target. Old smoothebore rifles were not accurate beyond 100 feet or more, but present day rifled firearms are highly accurate to several thousands of yards.
