For North American game, even big bears would you really be able to tell the difference?
The bear wouldn't, for sure.
I doubt the shooter would, either.
I'll admit, it helps to be a reloader to fully enjoy the 45-70. I think the .450 was set up for the non-reloader so hot ammo wouldn't end up in a Trapdoor, etc. That, to me, seems more of a legal liability issue than a ballistics issue. I can make my 45-70's walk side by side the .450 and not be embarrassed.
