Description: | G 18 // VIIZ
Description: Ball Mark VII was originally approved for service with a 160 grain spitzer bullet in March 1910, but this gave accuracy problems, and the cartridge was approved with a 174 grain spitzer bullet in November 1910 for land and naval service. The bullet is flat based with a two-piece core, the lower part being a lead/antimony alloy, the upper aluminium (or wartime substitute). With its enhanced muzzle velocity of 2,440 feet per second, this gave much improved terminal ballistics, and was a satisfactory solution to the shortcomings of the .303 Mark II and Mark VI cartridges. The 'Z' suffix indicates that this cartridge has a nitrocellolose propellant, rather than cordite. The Mark VII remained in British service until the .303 was phased out, but is still in use and production elsewhere in the world.
