I have to draw the line at 416 for heavy dangerous game. That is as big a cartridge I can shoot comfortably and accurately. After having shot a bunch of 375 H&H, 416 Rigby, 404 Jeffery (2nd favorite), 458 Winchester and Lott.
I have stated this before, I would comfortably take one of my 338-06's for anything huntable, with the exception of elephant or rhino. I do not see the extra 200 fps of the RPM as a huge advantage.
A .416 that you can shoot well would be better than a .458 that you can't. And when I say a .458, I mean a .458 that can launch a 500 grain projectile at 2300 fps from a cold barrel using a non-compressed load of a temperature-stable powder.
