Born from a desire for a faster and flatter shooting cartridge, the .32-20 Winchester Center Fire cartridge came to the world stage at the end of the 19th century as a popular option for revolvers and lever-action rifles alike, but its popularity eventually dwindled as the 20th century progressed.
Though largely forgotten and scarce today, the Colt 1871-72 "Open Top" revolvers represented an evolution in design for Colt, and ultimately paved the way for the Colt to transition from the cap-and-ball era to the cartridge era of the Single Action Army.
While there are many military rifles that have seen extensive service, the Italian M1870/87/15 Vetterli-Vitali stands out as one of the longest-serving military rifles in any guise.
It is said that the Winchester Model 1873 lever-action rifle is one of the guns that "Won the West." The same could also be said for its cartridge which still lives on to this day, the .44-40 Winchester, the history of which is explored here.
