Hornady's 30-150gr SST (Super Shock Tip) bullets are engineered for rapid expansion and deep penetration, making them suitable for a wide range of game, including whitetails and North American big game. The polymer tip enhances aerodynamics and initiates controlled expansion upon impact, while the InterLock® ring ensures the core and jacket remain bonded during expansion, retaining mass and energy for significant wound channels. The cannelure provides a consistent crimp location during loading, and the secant ogive profile offers low drag and a flatter trajectory for improved accuracy.
