What is indicated by the markings on the base of a bullet cartridge?

The markings on the base of a bullet cartridge typically indicate information related to the manufacturer and bullet caliber. This is crucial for identifying the specific type of ammunition and can help forensic and law enforcement professionals determine the origin and characteristics of the bullet in question. The manufacturer's name or logo, along with the caliber designation, provides valuable information that can be used in investigations.

This identification process aids in linking bullets to specific firearms during criminal investigations, and understanding the caliber can also give insights into the potential lethality and range of the bullet. As such, recognizing these markings is fundamental for evidence technicians in their work.
