The .257 Weatherby Magnum is a centerfire rifle cartridge developed by Roy Weatherby in 1944 as part of the Weatherby family of high-performance magnum cartridges. It is based on a necked-down .300 H&H Magnum case, which accommodates a .25 caliber (6.35mm) bullet. The .257 Weatherby Magnum is known for its high velocity, flat trajectory, and impressive downrange energy, making it an excellent choice for hunting medium-sized game at extended ranges.
The .257 Weatherby Magnum is suitable for hunting medium-sized game such as deer, antelope, wild hogs, as well as varmints and predators like coyotes and foxes. Its high velocity, flat trajectory, and excellent accuracy make it a highly effective cartridge for long-range hunting and shooting applications.
Typical bullet weights for the .257 Weatherby Magnum range from 75 to 120 grains, with muzzle velocities between 3,500 and 4,000 feet per second, depending on the bullet weight and load. The cartridge is known for its ability to maintain high energy levels at long distances, providing effective performance at extended ranges.
The .257 Weatherby Magnum is popular among hunters and shooters who demand superior ballistics and flat-shooting performance from a .25 caliber cartridge. While it generally produces more recoil and has higher ammunition costs than some other .25 caliber cartridges, the .257 Weatherby Magnum offers exceptional performance for those seeking a high-velocity, long-range hunting cartridge.
