This is .7mm Weatherby Mag. 120gr. Barnes TTSX Ammo. 7mm Weatherby was introduced nearly 20 years before the popular 7mm Remington Mag., the Weatherby version gives non-handloaders handloaded 7mm magnum performance. Delivers 400 fps more velocity than the 7mm Mauser. Ballistically similar to the .270 Weatherby Magnum with a larger selection of bullet weights, this cartridge is well-suited for any North American game as well as thin-skinned African game. The new Tipped TSX bullet 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 ballistic coefficient and improves long-range ballistics. The tip and a re-engineered nose cavity provide even faster expansion. This ammunition is new production, non-corrosive, in boxer primed, reloadable brass cases. This ammo comes packed in 20 round boxes.
