The .43 Spanish was a centerfire rifle cartridge developed by Remington designers around 1867.[2] It was used in early rolling block rifles that Remington manufactured for the government of Spain. The cartridge is also referred to as the .433 Spanish,[3] "11mm Spanish", and identical cartridges for the US Peabody rifle were marked "U.M.C. 43-77".[4]
History
The .43 Spanish cartridge was produced after Spain purchased the newly invented rolling-block action single-shot rifle. The breech-loading firearm, which was marketed by Sam Remington, impressed the Spaniards after their own evaluation.[5] In 1869, the Spanish government put in an order for 10,000 rifles.[6] In addition to the firearms, they wanted their own cartridge and Remington developed the .43 Spanish.[6] It was produced in two variants: the bottleneck case .43 Spanish (11.15x57mmR Remington Spanish) and the straight-wall case .43 Spanish Reformado (11.4x57mmR Reformado).[2]
The cartridge was very similar to the .44-77 Sharps cartridge, except for the difference in their case dimensions.[7] The Spanish military version of the cartridge was later upgraded in 1889 to a "heavier, brass-jacketed reformado bullet".[8] While Remington stopped manufacturing the cartridge in 1918, its use in the United States became widespread after World War II because it was sold as a surplus.[3]
"Poison bullet"
The .43 Spanish used a .454 in (11.5 mm) diameter bullet that weighed 396 gr (25.7 g). Its 1,280 ft/s (390 m/s) was powered by 74 gr (4.8 g) of black powder.[5] Instead of solid lead bullet, the .43 Spanish used a brass-jacket bullet, which was considered unusual because cupronickel, gilding metal, and copper clad steel were preferred for bullet jackets during the period.[9] It was also the reason why American soldiers suspected that the Spaniards used poison in their bullet during the Spanish-American War.[9] It corroded in the tropics, producing a powdery pale green verdigris once they are exposed to high humidity or salty sea air over time.[9] The brass component, however, improved bullet penetration.[9]
