A wildcat cartridge created in 1972 by Robert Chatfield-Taylor by necking down the .458 Winchester Magnum case to accept .416-caliber bullets. The result is a dangerous-game cartridge pushing a 400-grain bullet to approximately 2,350 fps — generating around 4,900 ft-lbs of energy — from standard bolt-action magazine lengths. It achieves performance comparable to the .416 Rigby in a more widely available case.
