With velocities up to 200 fps faster than standard loads, HyperSonic Rifle Bonded delivers more than just laser-flat trajectories and higher downrange energies. It zips through hide, meat and bone with unrivaled devastation thanks to today's most advanced bonded bullet design, Core-Lokt Ultra Bonded. Remington engineers started with a proprietary blend of propellants to achieve the boost in speed, then went to work to find the perfect lethal match, testing loads with every possible bullet design.
