Early in his elephant hunting, he had a 450/400 double. Always the experimenter, he rigged the triggers so that it would double with every shot, and he compared results with his .275.

His conclusion was that 800 grains in the wrong place don't kill them, and 170 grains in the right place kills them. So he'd rather carry a lighter rifle, and make darn sure that his bullets went to the right place.

He'd be mightily amused to see that 110 years on the debate still rages, and that hunters jump at each other's throat over "bigger is better" vs "shoot straight and you don't need bigger"...
