Ballistics
Velocity only, no drag model: no published ballistic coefficient is on file for .416 Taylor, so this is the shape gravity alone gives the advertised velocity. Drag would steepen it. The tool below solves real loads through their published G1 or G7 model.

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.
