Big difference between need and want. I do most of my hunting with a .45-70 of some type when I'm not carrying a muzzleloader or archery equipment. The loads I use would be adequate for elephant or should a stray cape buffalo walk through my woods in PA! I don't need it for deer or black bear, even though some of those PA bears are pretty big. I just enjoy that old cartridge and the lever guns it comes in.
Heck I even had a BFR in .45-70! but for how cumbersome that thing was I got rid of it. I may as well had been carrying a rifle.
