A cape buffalo would soak up a slug from a 45-70 like a sponge and then run someone over. In my opinion the 45-70 is a large, slow, sloppy, outdated caliber. I videoed a fellow a few years ago shooting a treed black bear with one and it did not even break the skull. Why he choose to shoot it in the head is any ones guess but that bear came out of the tree like a freight train and was killed by a .44mag on the ground. I'll leave the old buffalo gun for the history books.
