History
Robert Chatfield-Taylor developed the .416 Taylor as a practical alternative to the .416 Rigby for hunters who wanted dangerous-game performance without sourcing the scarce Rigby brass. By using .458 Winchester Magnum cases — already in wide use for African hunting — the Taylor could be loaded and chambered with familiar tooling. It gained a following among professional hunters and safari clients in the 1970s and 1980s before the .416 Remington Magnum and .416 Rigby became more commercially available.
