Since 1948, the Nosler Partition bullet has remained the gold standard in hunting ammunition, embodying the legacy upon which the Nosler company was founded. The bullet features a tapered copper-alloy jacket that ruptures immediately upon impact, causing the jacket to curl outward for uniform expansion. The dual-core design facilitates rapid expansion of the front core, while the Nosler partition reinforces the rear core, helping the bullet retain over two-thirds of its original weight for deeper penetration. With its unique lead-alloy dual-core, the Nosler Partition ensures reliable mushrooming and deep penetration at virtually all impact velocities, making it a versatile and effective choice for hunting all types of game. Nosler's unique lead-alloy, dual-core design ensures exceptional mushrooming performance across a wide range of impact velocities The Partition bullets in the Nosler line feature a dual-core construction, ensuring optimal length, weight, and ogive design for superior in-flight stability and terminal performance Special crimp locks enhance durability to withstand deformation when subjected to the pressure of heavy magnums Nosler's integral partition is designed to maintain the expanded mushroom shape while securing the rear lead-alloy core This enclosed rear core preserves over two-thirds of the bullet's initial weight, ensuring deep penetration
