Through an exclusive bonding process that eliminates voids in the bullet core, AccuBond® couples Nosler’s proven copper-alloy jacket with its special lead-alloy core. The result is a bullet that flies true, penetrates deep and retains its weight, without causing extensive barrel fouling. The unique white polymer tip resists deforming and initiates expansion on impact. Nosler’s Solid Base® at the rear of the bullet acts as a platform for large diameter mushrooms.
