The Hornady Interbond bullet uses a proprietary bonding process that holds the core and jacket together. Unlike partitioned or dual-core bullets, where the front core can separate from the bullet mass, the 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. Box of 100
