Description
.257 Weatherby Magnum 100 Grain Barnes TTSX~ 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-
100-PERCENT COPPER BODY
Since its introduction in 2003, Barnes’ TSX Bullet has earned a reputation as “the perfect hunting bullet.” Now, Barnes has improved on perfection by adding a streamlined polymer tip. The new Tipped TSX features the same 100-percent copper body with multiple rings cut into the shank. It delivers the same gnat’s-eyelash accuracy and “dead right there” performance—but with an added polymer tip that boosts BC and improves long-range ballistics. The tip and a re-engineered nose cavity provide even faster expansion. Complete penetration, virtually 100-percent weight retention and four razor-sharp cutting petals that double bullet diameter means the new Tipped TSX creates more internal damage than any competing bullet. Instant expansion and perfect penetration ensures cleaner, quicker kills.
