The .400 Corbon is an automatic pistol cartridge developed by Cor-Bon in 1997.[2] It was created to mimic the ballistics of the powerful 10mm Auto cartridge in a .45 ACP form factor. It is essentially a .45 ACP case, necked down to .40 caliber with a 25 degree shoulder. Nearly any .45 ACP pistol can be converted to utilize the .400 Cor-Bon cartridge with only a drop-in replacement barrel. [3]
This is a good cartridge with reasonable power with less recoil than the .45 ACP, because it uses less powder and lighter bullets. In addition, the bottleneck case can function better than a straight case with a wider variety of bullet shapes and sizes. Ballistics fall somewhere between the .40 S&W and the 10 mm Auto.[3]
