History

Developed by John Rigby & Company in 1911 for hunting African dangerous game. Specifically designed for stopping charging elephants and buffalo. Used extensively during golden age of African safari hunting. The large case operates at moderate pressures for reliable extraction in heat and dust. Fell out of favor mid-20th century but revived in 1980s-90s. Now considered one of the finest dangerous game cartridges.
