Weatherby‘s Select Plus line in .257 Weatherby Magnum (brand part no. B257100TTSX) pairs one of the fastest production cartridges made with a 100-grain Barnes TTSX bullet. This Tipped Triple-Shock X loading is rated at a .357 ballistic coefficient, a listed 3,570 feet per second muzzle velocity, and 2,830 foot-pounds of muzzle energy, numbers that put it at the extreme end of what a .25-caliber bullet can do. The TTSX is a lead-free, all-copper bullet whose polymer tip drives reliable expansion into four even petals while the solid copper shank holds together for deep penetration, giving the already-blistering .257 Weatherby a bullet built to survive its own velocity. For .257 Weatherby Magnum hunters who want the fastest factory load paired with a bullet that can take the speed, this rifle ammunition is built for exactly that.
