Well:
For what ever reason Winchester chose not to do so. I have been told in the past that they believed it would be difficult to get a magazine fed bolt action to feed this type of cartridge reliably. If this is in error so be it.
And considering the intended use of this rifle reliability was of primary importance.
However Winchester had no issues with chambering their Model 70 for the 375 Holland & Holland which is of course the parent case for the 458 Magnum.
I stand by my initial response that the 458 Magnum in the Winchester Model 70 filled a need perceived by Winchester for that American hunter making an occasional safari while retaining utility for other purposes and that was my whole intent in responding to this thread to begin with.
