Boomtube, where do people like you come up with this crap. And the one that posted "guides" prefer their sports to shoot 30-06's. FWIW Most of the guides I've talked to were off season cowboys and sheepherders and construction workers that knew considerably less about rifles than I do. Perhaps the outfitters should start asking the sports, "are you an average hunter?" What exactly is an "average hunter?"
I know absolutely nothing about the .300WSM. But I know a great deal about the 30-06 and the 7mmRM and the .300WM and the .338WM and the 8mmRM. I have shot them all and shot them enough to be quite capable with them. And if some bath-a-year guide started trying to tell me what rifle I should be using, he'd be looking for another client.
You folks that want to make broad, sweeping statements in an attempt to appear knowledgable do just the reverse.
