400 Cor Bon

New drawing Coming

The .400 Cor-Bon is a high-performance pistol cartridge developed in the late 1990s by Peter Pi, Sr., of Cor-Bon Ammunition. It is essentially a .45 ACP case that has been necked down to accept a .400 inch (10mm) bullet. The necked-down design improves the cartridge's ballistic performance, offering higher velocity and energy compared to the standard .45 ACP.
The .400 Cor-Bon is designed for use primarily in semi-automatic pistols, particularly those originally chambered for .45 ACP, as the cartridge dimensions allow it to fit within the same magazine and frame dimensions. Popular for self-defense and hunting, the .400 Cor-Bon delivers potent stopping power and increased penetration.
Typical bullet weights range from 135 to 165 grains, with velocities reaching up to approximately 1,300 to 1,500 feet per second, depending on the load. Due to its high velocity and relatively flat trajectory, the .400 Cor-Bon is appreciated for its accuracy and effective performance over varying distances.
Noteworthy is the need for proper handloading practices if customizing ammunition, as improper loading can lead to excessive pressures. The .400 Cor-Bon is less commonly found than other mainstream cartridges and may require specific searches to find commercial ammunition.
