The 45-75 W.C.F. was designed for, and used almost exclusively in the Winchester Model 1876 lever-action rifle. When Winchester introduced the Model 1886 lever-action 10-years later in the more powerful (and popular) 45-70 cartridge, the Model 1876 quickly faded into obscurity, though Winchester did continue to make 45-75 cartridges up to the year 1935.
