Also known as the .275 Rigby, the 7x57mm Spanish Mauser round came about when Mauser won the military contract from the Kingdom of Spain to supply rifles and ammunition in 1892. Paul Mauser delivered trial rifles that used what was then new smokeless powder, otherwise known as Poudre B. The initial rifles were then improved with an internal box magazine so that the cartridges could be stored in a column ready for chambering. The Spanish military contract Mauser rifle won its maker the Grand Cross of the Spanish Military Order of Merit. During the Spanish-American War of 1898, the US military realised that the 7x57mm Spanish Mauser outperformed their government issue 30 40 Krag rifles, with high casualties sustained by the Americans. The 30-03 and 30-06 rounds were developed for the US military in response to the better firepower of the Spanish 7x57mm Mausers. The British Army also found that 7x57mm rifles in the hands of Boers during the Boer War outranged the Lee Enfield .303 round nose bullet, and modernised the .303 cartridge to adapt. Early 7x57mm Spanish Mauser rounds were fitted with a round nose bullet, but by 1913, a lighter spitzer shape was found to improve performance even more because of reduced drag. Price is for ONE round only. Rounds must ship with courier.
