I stated in my first reply on this topic that the .416 Remington is a more practical choice, in my opinion more because of the greater selection of .416 diameter bullets vs. .411s. I’ve got a Model 70 in .416 Rem built by the Winchester Custom Shop in the early 90s and it feeds and extracts just fine but not as slick as my .400 H&H Dakota. That does not mean much as it’s just a sample of two rifles. I do believe the long gently tapered cases of the .300, .375 and .400 H&H promote good feeding and easy extraction. Your right it is an example of “rifle loonyism”.
