History: A large-bore Peabody single-shot rifle cartridge designed for military trials and target competition in the 1870s. The 50-grain powder charge made it a modest-sized military cartridge compared to .45-70. Used in trials comparing various single-shot military rifle systems before bolt-action repeaters made all such designs obsolete.
