(Talking completely from an armchair)

I would choose a 416 Chatfield-Taylor if I wanted a (semi-)wildcat in a standard length action. Maybe a lighter rifle for carrying rather than shooting, as Orion would say.

If I wanted the same in a factory rifle where I could buy ammunition or reloading supplies (eg cases) easier then I would go for the 416 Remington. Personally I wouldn't unless I had no other choices.

The 416 Rigby is a true classic and that's what I would go for. It will be a magnum action, but factory rifles, ammunition and reloading components are accessible.

Then again I would be in a quandary and have to choose between the Rigby and a .404 Jeffrey also a standard action cartridge and also a classic.
