The .45 Long Colt cartridge, developed in 1872, is a powerful revolver round originally intended for the U.S. Army’s Colt Single Action Army revolver. It fires a large-diameter, heavy lead bullet, typically ranging from 230 to 260 grains. This makes it a substantial cartridge with considerable stopping power.
Its historical significance and continued popularity are rooted in its effective performance in hunting and personal defense. The heavy bullet provides significant energy transfer, making it suitable for taking down medium-sized game such as deer or wild hogs. While superseded by more modern cartridges in military applications, it remains relevant in civilian markets due to its simple design and reliable function in appropriately chambered firearms. This enduring appeal also sustains the production of firearms specifically designed for this classic cartridge.
