Good points. From a theoretical point of view I would agree.
As I already have .300 Weatherby dies & several hundred rounds of .300 Weatherby ammunition, and I do like the performance of the .300 Weatherby, it makes sense to look for that chambering.
A big game rifle being a powder eater isn't much of an issue to me as I don't shoot many rounds through the larger rifles each year. A small-game weapon needs to be efficient but from my perspective a big game rifle needs to be devastating. I have many choices in the safe if I want to be efficient: .22 short, .22 long rifle, .223, .243, .25-06 (that I most often carry), and .260. Then I jump up to the less efficient: 7MM rem, .300 Weatherby, the real powder burner: my .338/378 Weatherby mag., and a .375 H&H.
