Millions of successful hunts have proven the accuracy and deadly knockdown power of the famous Hornady InterLock, SST and InterBond bullets loaded into every Hornady Custom rifle cartridge. Each cartridge is loaded to ensure optimal pressure, velocity and consistency, from lot to lot. This Custom series ammo features the SST (Super Shock Tip) bullet, designed to deliver tremendous shock on impact while expanding quickly and reliably, particularly at higher velocities. This load is ideal for medium (50-300 lbs) game.
