The Norma BondStrike 300 Winchester Magnum hunting ammo pushes a 180-grain bonded polymer tip to 3084 feet per second from a 26-inch test barrel, generating 3802 foot-pounds of muzzle energy. This 300 Winchester Magnum hunting ammo uses power bonding technology—jacket and core molecularly fused during manufacture—to retain mass through heavy bone and deliver terminal expansion from 50 to 500 yards. The 0.615 G1 ballistic coefficient rivals match-grade projectiles while the thinner front jacket initiates expansion at extended ranges where conventional hunting bullets pencil through.
Load Profile
Norma engineers the BondStrike around a boat-tail base and aerodynamic polymer tip, maintaining supersonic velocity past 1,000 yards in standard atmospheric conditions. The bonded construction—core and jacket molecularly fused rather than mechanically swaged—prevents jacket-core separation when the bullet encounters heavy shoulder blades or femurs on elk-sized game. Brass cases carry Boxer primers for handloaders planning future reloads; Norma holds case wall thickness tolerances to ±0.0005 inch across production lots.

This load fits hunters running magnum-length actions for elk, moose, or brown bear at distances where conventional cup-and-core bullets lose expansion reliability. The match boat-tail and high ballistic coefficient flatten trajectory and reduce wind drift compared to flat-base hunting designs in the same weight class.

Safe Handling & Compliance
Federal law requires purchasers to be at least 18 years old for rifle and shotgun ammunition, and at least 21 for handgun ammunition. Ammunition cannot be shipped to certain states, counties, and cities — review our ammunition shipping restrictions before ordering. Store ammunition in a cool, dry location away from heat sources and out of reach of unauthorized users.
