Product DescriptionNosler Partition bullets are engineered for dependable in-flight accuracy and controlled terminal performance across a wide range of impact velocities. Each bullet uses Nosler's dual-core Partition design with a fully tapered copper-alloy jacket that initiates expansion quickly at the nose while the integral partition supports the mushroom and helps the rear core retain significant weight for deep, consistent penetration.
