What is 440 cor-bon?

.440 Cor-bon is a cartridge designed by the Cor-bon company in 1998. It is a powerful handgun cartridge that was derived from the .50 Action Express cartridge by necking down the case to accept a .44 bullet. The .440 Cor-bon delivers a muzzle energy of around 960 foot-pounds, making it suitable for hunting and self-defense purposes.

The bullet diameter for the .440 Cor-bon is .429 inches, and the cartridge length is 1.285 inches. It has a slightly shorter overall length than the .45 ACP, making it more easily concealable in a compact handgun. The .440 Cor-bon has a reputation for being an accurate cartridge, with a flat trajectory and high velocity.

However, due to its relatively short lifespan, the .440 Cor-bon has never gained mainstream popularity. In recent years, the cartridge has been largely superseded by newer, more powerful handgun cartridges such as the .500 S&W Magnum and the .460 S&W Magnum.
