Not one. But I have shot a hell of a lot of big animals with a 45-70, and it puts all of them down RIGHT NOW. Zebra, blue wildebeast, black wildebeast, American bison, elk, you get the idea. Complete pass through penetration with a .458 bullet has a way of killing things, and a lion or tiger is not harder to shoot through than a zebra or a 2000 pound bison.
I have seen too many dvd's of animals being shot in Africa with a 375 or 416 to think they work better than a properly loaded 45-70. I actually have a 375 H&H FWIW, and it won't penetrate with my 45-70.
