Quick Answer
The .257 Weatherby Magnum is a suitable cartridge for antelope hunting, offering a good balance of power and precision for medium-sized game.
Ballistic Performance
The .257 Weatherby Magnum’s ballistic performance makes it an attractive choice for antelope hunting. With a muzzle velocity of approximately 3,800 feet per second and a flat trajectory out to 400 yards, this cartridge can deliver a lethal hit to the animal. The cartridge’s kinetic energy at 300 yards is around 1,200 ft-lbs, sufficient to drop a medium-sized antelope.
Gun and Bullet Selection
When selecting a rifle for .257 Weatherby Magnum hunting, look for a rifle with a barrel length of at least 24 inches to take full advantage of the cartridge’s velocity potential. A heavy bullet with a flat profile, such as the 100-grain Barnes TSX or the 110-grain Sierra MatchKing, will provide the necessary stopping power for antelope. A 1:9 to 1:10 twist rate is suitable for these bullet weights.
Hunting Techniques
When hunting antelope with a .257 Weatherby Magnum, use a shooting distance of 150 to 250 yards, where the cartridge’s trajectory is most stable. Engage the animal with a well-placed shot to the lungs or heart, aiming for a 2-inch circle. A good hunting spotter or rangefinder will help you accurately gauge the distance to the animal, ensuring a clean shot.
