The hornady interbond bullet holds together in a single destructive mass that delivers a deep wide wound channel without over-penetrating.The bonding process along with a thicker stiffer jacket allows interbond bullets to retain more than 90% of their mass even through tough hide and bones.Plus they immediately expand to more than twice their diameter for maximum energy transfer.Its sleek polymer tip improves ballistic performance accuracy and initiation of expansion.Coefficient: .480Bullet Type: InterBondBullet Diameter: .308Weight: 180 grBullet Caliber: 30 CaliberJacket Material: CopperBullet Tip Material: PolymerCore Material: LeadSectional Density: .271Quantity: 100 Per Box
