.577 Snider with the coiled brass case. This is an externally primed centerfire cartridge for the British Snider rifles and carbines. The Sniders came along about the same time as the Springfield Trapdoors. The design was created by an American who offered his conversion method to the U.S. but was turned down. He then took the idea to the British where it was adopted. The British Snider rifles and carbines were used well into the next century, especially in areas like India and Afganistan.
