Cartridge Hall of Fame: 45 Colt Ammunition | MidwayUSA
This video delves into the history and significance of the 45 Colt cartridge, also known as 45 Long Colt. Introduced in 1873 as a joint effort between Colt and the Union Metallic Cartridge Company, it was developed for the Colt Model 1873 Single Action Army and served as the official Army handgun cartridge until 1892. Original black powder loads produced around 560 foot-pounds of muzzle energy. Standard modern loads feature a 255-grain bullet exceeding 900 feet per second, with specialty loads available for modern revolvers like the Ruger Blackhawk.
