The .577-450 Martini-Henry cartridge is a late 19th-century British service round designed for use in the Martini-Henry rifle. It evolved from the earlier .577 Snider cartridge and features a bottle-necked profile. The cartridge combines a .577-inch (14.7 mm) base with a .450-inch (11.43 mm) neck, resulting in a unique shape.
The original loading consisted of a 480-grain (31 g) lead bullet propelled by 85 grains (5.5 g) of black powder. This round was used extensively from its introduction in 1871 until it began to be phased out in the late 19th century.
The .577-450 Martini-Henry cartridge was influential in various British colonial conflicts, such as the Anglo-Zulu War. It is known for its considerable stopping power and long-range effectiveness in military engagements.
Specialty ammunition also exists for enthusiasts and collectors who still shoot Martini-Henry rifles today, including modern smokeless powder versions and reloading supplies.
