The Hornady American Whitetail 7mm-08 Rem 139gr is a highly efficient hunting cartridge that leverages the 7mm-08's reputation for mild recoil and exceptional terminal performance. This load features the SST® (Super Shock Tipped) bullet, which uses a sharp polymer tip to streamline its flight path and initiate rapid, devastating expansion upon impact. To prevent the bullet from breaking apart at high velocities, it is constructed with the InterLock® ring, a mechanical feature that keeps the lead core and jacket together for deeper penetration and higher weight retention. With a muzzle velocity of 2,840 FPS, this ammunition is specifically tailored to provide the flat trajectory and reliable energy transfer required for ethical one-shot kills on whitetail, mule deer, and antelope.
