HORNADY 270-150gr IB (100)

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.
