Precision defines the quality of components and loads selected for Norma's American PH line-up. Production at Norma starts with the highest quality brass cases available in the industry, Norma powder, and bullets specifically selected for North American big game. Most loads feature Norma's tried and true Oryx bonded bullet for maximum penetration and near 100% weight retention. To ensure perfect mushrooming, the Oryx has a thin forward Jacket with internal splitting zones and a thicker rear jacket to ensure high residual weight after impact. The Oryx has rapid expansion, excellent penetration and high energy transfer, perfect for the North American Big Game hunter.
