Breech Loading Cartridge Rifle

This is a Colt Model 1878 Double Barrel Sporting rifle, chambered in .45–70 Government centerfire, combining the era’s powerful cartridge with a double-barrel configuration. Built for big-game hunting and frontier sport, it offered shooters a fast second shot and rugged performance in the field. Today it is valued for its uncommon design, robust construction, and place in late-19th-century American firearms history.
