Brad, the question has been asked many times:
What Africa/dangerous game capable cartridge will fit a std. length action, and allow for a lighter, handier rifle (read 22-24" barrel and lower cartridge weight) for serious Alaska, B.C. and Yukon grizzly/brown bear and Africa use?
The answer was the .375 Taylor.
The new answer appears to be the .375 Ruger.
Brad, the other thing is that I have a .300 Win. Mag. It's apparently not based on the .338 win mag but on the 300 win. mag. I can maybe use some of my extra brass interchangeably (same platform) for north america hunting and have the same bolt throw?
