I own both Marlin .45/70 and S&W 500 revolver and would rate them reasonably equal in power. The ballistics are not too dissimilar and although I obviously don't have a high kill tally with the .500, I have killed a few hundred head with various .45/70's to know what 400 grain bullets can do in the high teens for velocity.

Let me explain it by saying that I do not believe you would pick one over the other for any particular hunting chore. You simply carry what please you. I know I would.

When truth is ignored, it does not change an untruth from remaining a lie.
