Either one will do you just fine. I've had a 338 WSM for 5 years or so and like it. IMO, there isn't one thing you could do with one that you couldn't with the other.
As for being 50 feet from a po'd buff, I'd want a gun I was very intimate with and the cal to a great degree wouldn't matter with me. IMO at that time it's time for one perfectly placed round and precision will trump power. I'd not sweat it one bit if it was a 338, but that's just me. As long as I knew it very well.

Yep I'm 100% in agreement
