The 577 Snider round comes from the a period of rapid development in the evolution of the modern brass cartridge. The 577 Snider round originally used a wrapped brass foil casing, although later manufacture utilised drawn cases which are stronger. Snider mechanisms were used in the USA to convert US Civil War era muzzle loading rifles to breech loading. The British Army took Snider mechanisms and fitted them to their rifles at Enfield. 577 Snider rounds were adopted together with the modified rifles between 1866 to 1867. The 577 Snider inert round is fitted with a Minie ball lead head, which is a period-accurate, hollow base bullet head designed in 1849 by CE Minie. Case is made from spun brass. Price is for one round only. Rounds must travel with courier.
