The Weatherby 416 WBY Mag 350gr Barnes TTSX load is a box of 20 rounds of 416 Weatherby Magnum hunting ammunition built on premium brass (Weatherby part no. B416350TTSX). Weatherby says the 416 Weatherby Magnum, a necked-up version of the 378 developed by Roy Weatherby son Ed, has quickly become one of the best all-around cartridges for Africa. 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. Each box holds 20 rounds, so one purchase covers a range session to confirm zero and a few shots in the field. The company says it exceeds the power and energy of the 416 Rigby, the 416 Remington Magnum and the 458 Winchester Magnum, and calls it the ideal choice for a single-gun African safari or Alaska big bears.
