The .270 Weatherby Magnum is a high-velocity rifle cartridge developed by Roy Weatherby in 1943. It's based on the .300 H&H Magnum case, necked down to accept a .277-inch (7mm) diameter bullet. Known for its flat trajectory and high-speed performance, this cartridge is capable of pushing bullets at speeds exceeding 3,200 feet per second (fps), making it effective for long-range shooting.
Use cases for the .270 Weatherby Magnum include big game hunting, such as deer, elk, and antelope, given its powerful ballistic performance. Its flat shooting characteristics also make it suitable for open terrain where longer shots are common. Due to its high velocity and energy, this cartridge provides excellent terminal performance on a variety of game animals.
In summary, the .270 Weatherby Magnum is a powerful, effective cartridge designed for high-velocity shooting and long-range big game hunting.
