I think this thread is a good example of why resurrecting an old thread for more discussion is not necessarily a bad thing.
i have two .338-06 (standard versions) and a .35 Whelen AI. The Whelen feeds very smooth in its Mauser action with no mods (was born a Husky M98 30-06)
Do whatever you like on your build. I think the AI is cool, even though neither of mine is an AI. The basic .338-06 is great too and you'll love it as well.

Best of luck,
Rex
