It's fair to say that hypersonic bonded is the most lethal big-game ammunition ever engineered.With hyper-charged velocities up to 200 fps faster than standard loads, it delivers laser flat trajectories and higher downrange energies.Simply put, it plows through hide, meat, and bone like a hot knife through butter.By pairing the most advanced bonded bullet design of core-lokt ultra bonded with a proprietary blend of propellants, hypersonic bonded is a high-velocity load that's second to none.Caliber: 300 Win MagBullet Type: PSP Core Lokt Ultra BondedBullet Weight: 180 grMuzzle Energy: 3890 ft lbsMuzzle Velocity: 3120 fpsRounds Per Box: 20Boxes Per Case: 10Application: HuntingCasing Material: BrassHazair: Yes
