11.5X57Rmm / .43 Spanish Reformado

11.5X57Rmm / .43 Spanish Reformado
Warning! Notes: Historical Notes: This was the original centerfire, Berdan-primed Spanish military cartridge. It was adopted about 1867 and used in early rolling-block rifles manufactured by Remington for the Spanish government. It was also used in some Berdan and Snider conversions of the Spanish muzzleloader. Over a million rounds of this ammunition and many rolling-block rifles were captured by American troops in Cuba during the Spanish-American war. It was replaced by the 11.15mm Spanish Remington cartridge in 1871. General Comments: Although this cartridge is listed as 43-caliber, the bullet has a base band that is actually 0.454-inch in diameter. The bullet is brass covered and has a 10-degree beveled base. Rim and base diameter and case length are almost identical to the 11.15mm Spanish Remington and cases could be made by expanding and trimming 11.15mm cases. (Cartridges of the World 12th Edition)
