There are many cartridges which use 7.62 mm caliber bullets. Historically, this class of cartridge was commonly known as .30 caliber, and was most commonly used for indicating a class of full power military Main Battle Rifle (MBR) cartridges. The measurement equals 0.30 inches or 3 decimal lines, written .3″ and read as Three-Line.^[1]

7.62 mm refers to the diameter of the lands in the barrel (the raised helical grooves in rifled gun barrels). The actual bullet caliber is normally .308 in (7.82 mm), although Soviet weapons commonly use a .311 in (7.91 mm) bullet, as do older British (.303 British) and Japanese cartridges.
