The Weatherby 240 WBY Mag 80gr Barnes TTSX load is a box of 20 rounds of 240 Weatherby Magnum hunting ammunition built on premium brass (Weatherby part no. B24080TTSX). The 240 Weatherby Magnum (in production since 1968) is a 6mm-caliber magnum that Weatherby says is, on average, considerably faster than any existing standard 6mm cartridge. The Barnes TTSX is a 100-percent copper bullet with a polymer tip that raises ballistic coefficient and starts expansion quickly, opening four cutting petals to roughly double the bullet diameter. The 80-grain bullet carries a published ballistic coefficient of .333, a number that tells you how well it holds its speed downrange. That speed means more striking energy at the target and less bullet drop at longer ranges.
