What term describes the grooves inside the barrel of a firearm that give it unique characteristics?

• A. Barrel markings
• B. Rifling
• C. Chamber patterns
• D. Cartridge impressions

Answer: (B)

The grooves inside the barrel of a firearm that provide unique characteristics are referred to as rifling. Rifling involves the helical grooves cut or machined into the interior of the firearm's barrel. These grooves are designed to make the bullet spin as it travels down the barrel, which stabilizes the projectile in flight and improves accuracy. Furthermore, rifling leaves distinctive markings on the bullets when they are fired, allowing forensic experts to match recovered bullets to a specific firearm. Each barrel has a unique pattern of rifling that varies in terms of the number of grooves, their depth, width, and the twist rate, making it a key element in firearms identification during investigations. Barrel markings are a broader category that includes all impressions left on a bullet by the barrel, while chamber patterns refer to features specific to how cartridges are stored in the firearm. Cartridge impressions specifically relate to marks left on the casing of a fired round, which is different from the internal grooves of rifling.
