Millions of successful hunts have proven the accuracy and deadly knockdown power of the bullets loaded into every Hornady Custom rifle cartridge. Custom ammunition balances expansion and penetration and is well-suited to medium and large sized game. The powder and primer are carefully matched to individual loads, and every round is hand inspected before packaging to ensure the highest levels of quality control. Hornady manufactures Custom ammunition to give shooters and hunters the advantage of handloaded accuracy in a factory load. This ammo is loaded with Hornady's InterLock SP bullets which features a raised ring inside the jacket embedded in the bullet's core to keep core and jacket locked together during expansion to retain mass and energy. It utilizes the ballistically efficient secant ogive design and has an exposed lead tip for controlled expansion and hard hitting terminal performance.
