The Hornady American Whitetail 7mm Rem Mag 154gr is a high-velocity hunting cartridge designed to maximize the long-range potential and hard-hitting energy of the 7mm Magnum platform. It features the SST® (Super Shock Tipped) bullet, which utilizes a polymer tip to increase its ballistic coefficient and initiate rapid, devastating expansion upon impact. To ensure the bullet maintains its structural integrity at magnum velocities, it is engineered with an InterLock® ring that mechanically locks the lead core to the jacket for consistent weight retention and deep penetration. With a muzzle velocity of 3,035 FPS, this ammunition is specifically optimized to deliver the flat trajectory and "knock-down" power required for ethical one-shot kills on whitetail, mule deer, and similarly sized game across open terrain.
