I don't know that there would be a practical reason for a .338X57. Better bullet selection?

 

338x57 might be a good candidate for a rebore when trying to save a shot-out sporter barrel.

There was a common wildcat cartridge in the 50 and 60's nicknamed the "Poorman's Magnum". It was reverse of your idea. It was a 338 mag case necked down to 8MM. It was a way to magnumize a surplus rifle without a new barrel. Unlikely today one could find a gunsmith willing to ream the chamber because of the possible liability.
