No question that the 450 Rigby can push the 500 grainers faster, but to what effect??

A 500 grainer at 2150+ will penetrate and kill everything that walks so I am at a loss what the higher velocity 450 Rigby does other than give more standoff capability.

If I want more gun a larger diameter bullet seems a better approach.

The same arguement can be said about the 375 H&H vs Weatherby 378. Great ballistics but to what purpose?

Would I love to have a 450 Rigby?? Of course!!
Is it a superior weapon to a 458 Lott?? Dunno, but I suspect not.

I obviously admit I have never hunted Africa with either--Am I all wrong on this??
