See DealThe 450 Rigby, sometimes known as the 450 Rigby Magnum Rimless, is a rimless, bottlenecked cartridge with a caliber of.45 caliber (11.6 mm) designed for hunting big hazardous wildlife. The cartridge is based on a.416 Rigby that has been necked up to take a.458-inch (11.6 mm) bullet. The cartridge is designed for magazine rifles and is not to be confused with Rigby's.450 Nitro Express, which was released in 1898. The CIP regulates and regulates the.450 Rigby dimensions and specifications. A bore diameter

of 11.43 millimeters (0.450 in) and a groove diameter of 11.63 millimeters are recommended by the CIP (0.458 in). The barrel will feature a six-groove rifling profile with a twist rate of one revolution per 420 mm (17 in) and a groove width of 3.60 mm (0.142 in). Maximum pressure of 4,000 bar is specified by CIP (58,000 psi).
The 450 Rigby, unlike many modern.458 caliber dangerous game cartridges, was designed to run at lower pressures. The maximum pressure restriction imposed by CIP is 4,000 bar (58,000 psi). With the 500-grain (32 g) bullet, the cartridge readily reaches the target 2,300–2,400 ft/s (700–730 m/s) at these pressures. In tropical settings, where the cartridge is designed for usage, the lower pressures enable improved operating dependability. With the 500 gr (32 g) cartridge, the 450 Rigby easily approaches the coveted 2,400 ft/s (730 m/s) velocity record while staying well within the CIP pressure limitations.
The 450 Rigby was created with the intention of hunting large, thick-skinned dangerous game animals in Africa. Due to the cartridge's performance, it would be a superior cartridge for certain game animals, such as African elephants, Cape buffalo, rhinoceros, and maybe hippopotamus, than the standard standby cartridges..450 Rigby For Sale
