7.62 mm caliber is a nominal caliber used for a number of different cartridges. Historically, this class of cartridge was commonly known as .30 caliber, the Imperial unit equivalent, 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.
7.62 mm refers to the internal diameter of the barrel at the lands (the raised helical ridges in rifled gun barrels). The actual bullet caliber is normally 7.82 mm (.308 in), although Soviet weapons commonly use a 7.91 mm (.311 in) bullet, as do older British (.303 British) and Japanese cartridges.
There are many pistol cartridges in this caliber, but most common are:
The 6.5×54mm Mannlicher–Schönauer also known as 6.5×54 Mannlicher–Schönauer Greek is a 6.5 mm (.264" cal.) rifle cartridge used in the Mannlicher–Schönauer rifle. 6.5 mm bullets are typically known for their high ballistic coefficients and sectional density, which gives them great stability in flight, resistance to wind deflection, and excellent penetration.
Walter Dalrymple Maitland "Karamojo" Bell, who shot more than 1,500 elephants in the period 1895-1930, had a very high regard for the 6.5mm Mannlicher–Schoenauer, using it for approximately 300 of these kills. Daniel Fraser of Edinburgh, Scotland built him a special, lightweight rifle in that calibre. He only set it aside when he was unable to acquire dependable ammunition for it, and turned to a .275 Rigby Mauser magazine rifle instead. The .275 Rigby cartridge is interchangeable with the 7×57mm Mauser. Bell's legendary name has remained closely linked with the 7mm Mauser, but the 6.5 Mann.–Sch. was his first preference.
Mega Man X7, known as Rockman X7 (ロックマンX7) in Japan, is a video game developed by Capcom for the PlayStation 2 (PS2) console.

Mega Man X7 takes place in the 22nd century. Daily human life is often disrupted by "Maverick" crime from the "Reploids" robots that live and work amongst them. The heroic "Maverick Hunter" Mega Man X has retired from the battlefield. As such, various groups have begun springing up to stamp out the ever constant threat of Maverick activity. Axl, a member of "Red Alert", questions his group's methods and escapes, only to be pursued by its leader, Red. Like other games in the series, Mega Man X7 is an action-platform game in which the player fights through an octet of selectable stages. The game differs from previous side-scrolling entries by featuring fully 3D graphics intermixed with both 3D and 2D gameplay.
