Owning a piece of history like Teddy Roosevelt's Winchester 1876 in 45-75 would be a nice place to start.
Ah, the .45-75. It was developed as a shorter, bottlenecked version of the .45-70 because Winchester could not get the 1876 rifle to work with the .45-70's length. But the .45-70 was so popular that Winchester had to get it into a lever gun which led to the great 1886 Winchester. Which was maybe the best levergun ever. Winchester gave the illusion that the .45-75 was more powerful than the .45-70 but it was not.
