Description
.257 Weatherby Magnum 115 Grain Barnes TSX~ The .257 Weatherby Magnum is a .257 Caliber (6.35 mm) belted bottlenecked cartridge. It is one of the original standard length magnums developed by shortening the .375 H&H Magnum case to approx. 2.5 in (64 mm). Of the cartridges developed by Roy Weatherby in 1944, the .257 Weatherby Magnum was known to have been his favorite, and the cartridge currently ranks third in Weatherby cartridge sales, after the .30-378 Weatherby Magnum and the .300 Weatherby Magnum.
The .257 Weatherby Magnum is among one of the flattest shooting commercial cartridges. The .257 Weatherby Magnum shares the same cartridge case as the .270 Weatherby Magnum and the 7mm Weatherby Magnum. The .30 Super Belted Rimless H&H manufactured by Winchester served as the direct parent cartridge for the case design. The .257 Weatherby Magnum was one of the first cartridges which used the shortened, blown out and necked down .375 H&H Magnum case and served as the forerunner to the standard length magnum cartridges such as the 7mm Remington Magnum and the .338 Winchester Magnum. There has been some speculation that Roy Weatherby may have used the full length .375 H&H Magnum case if he had slow burning powders available today when the cartridge was designed.

The Bullet–
Barnes’ most popular hunting bullet, the TSX™ Triple Shock® X-Bullet utilizes all-copper construction and innovative design to give you one of the deadliest, most dependable bullets you can buy. More than 20 years of copper bullet experience go into the TSX, delivering a bullet that gives you lower fouling, better accuracy, greater velocity and lower pressure. The TSX’s all copper construction delivers a lighter bullet than comparable lead core bullets, delivering higher velocities, flatter trajectories, and less recoil. This construction also delivers nearly 100% weight retention and produces surer, deeper penetration with its specially engineered nose cavity that peels back into four sharp-edged petals that cut through game. This specially designed nose cavity expands to double the bullet’s diameter almost immediately after impact at both high and low velocities, giving you a bullet that is as deadly on longer shots as it is at point blank range. The Triple-Shock X also features multiple precisely engineered rings cut into the bullet shank that serve as relief valves as the bullet travels down the bore. These rings give the bullet’s copper material a place to expand into under pressure, resulting in reduced pressures, less copper fouling, and better barrel harmonics for improved accuracy. Recommended by big game guides around the world. Made in USA.
