AccuBond represents the most advanced bonded core bullet technology to date. Through a proprietary bonding process that eliminates voids in the bullet core, AccuBond marries Nosler’s traditional copper-alloy jacket with its special lead-alloy core. The result is a bullet that flies true, penetrates deep and retains its weight—and won’t cause extensive barrel fouling. Nosler AccuBond--the benchmark by which all bonded core bullets will be measured. The fully tapered, heavy alloy jacket is bonded to the special lead alloy core through a proprietary process designed for controlled expansion, deep penetration and 60-70% weight retention. Totally concentric, impact extruded jacket bonds completely to the bullet core for extreme accuracy. The AccuBond bullet's polymer tip resists deformation in the magazine and initiates expansion upon impact. Nosler Solid Base design jacket base acts as a platform for large diameter mushroom. Ballistically engineered Solid Base boat tail configuration combines with the streamlined polymer tip for extreme long range performance. This is not loaded ammunition.
