. The .45-75 was shorter and fatter than the .45-70 government cartridge. Although the .45-75 was nominally superior to the popular .45-70, the weak toggle-link action with its elevator-style carrier originally designed for handgun cartridges limited the ability of the Model 1876 rifle to safely fire higher pressure loads intended for stronger actions. Within a decade, the Model 1876's advantage of faster loading for subsequent shots was eclipsed by the stronger and smoother Winchester Model 1886 action capable of handling longer cartridges, including the .45-70 with varying lengths for 300 and 500 grain bullets. The Kennedy lever-action rifle manufactured by Whitney Arms Company was also chambered for the .45-75. The .45-75 and similarly short .40-60 Winchester, .45-60 Winchester, and .50-95 Winchester Express cartridges designed for the Model 1876 rifle faded into obsolescence as 20th-century hunters preferred more powerful
