Weatherby’s Select Plus ammunition in .300 Weatherby Magnum (brand part no. B300180TTSX) loads a 180-grain Barnes TTSX bullet at a blistering 3,240 feet per second, pairing the cartridge that redefined magnum performance with one of the toughest hunting bullets Barnes builds. Weatherby introduced .300 Weatherby Magnum in 1944, and it remains the flattest-shooting, hardest-hitting .300 magnum most hunters will ever need. The TTSX (Tipped Triple-Shock X) is a monolithic all-copper hollow point whose polymer tip drives reliable expansion while the copper body sheds no weight, so it drives deep and straight through heavy game. For hunters who want maximum reach and terminal performance from a true long-range magnum, this rifle ammunition is built for the biggest game on the continent.
