There is a .338 Winmag.

Actually shot a wild pig in the face with one two weeks ago...

The .30-.338 Winchester Mag. was developed back in 1958 by Fred Huntington for 1000 yard benchrest competition. It basically duplicates .308 Norma Mag. ballistics. I would suggest contacting the people at IMR at help@imrpowder.com to get some recommended starting load data.
