20 rds. Remington® HyperSonic Centerfire Ammo. Up to 200 F.P.S. faster than standard loads!

Give your shot a HyperSonic boost! With hyper-charged velocities up to 200 fps faster than standard loads, Remington HyperSonic Centerfire 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 on ballistic gel, simulated bone, actual big-game carcasses and other mediums we can't reveal. When the smoke and the chunks cleared, the combination that dominated in terminal performance and accuracy is the one you see here. No other high-velocity load on the market can measure up!
