For hunters pushing 300 WSM ammo past conventional ranges, the Norma BondStrike 180-grain bonded polymer tip load delivers match-grade ballistic coefficients without sacrificing terminal performance. A 300 Winchester Short Magnum cartridge is a high-intensity magnum round optimized for short-action rifles, offering 300 Winchester Magnum velocity in a more compact package. The BondStrike bullet combines an aerodynamic polymer tip with proprietary power-bonding technology—a mechanical interlocking process that prevents core-jacket separation through heavy tissue and bone. At 3084 fps from the muzzle, this load generates 3802 ft-lbs of energy, placing it squarely in the elk, moose, and heavy-bodied game category.
Built for the Box
Norma engineers the BondStrike line with thinner front jackets designed to expand reliably at extended distances where velocity drops below 2200 fps. The polymer tip initiates expansion on impact, while the bonded core holds together through dense shoulder muscle and heavy bone. The boat-tail base and tangent ogive produce a high ballistic coefficient—comparable to match ammunition—reducing wind drift and extending maximum point-blank range. Each 20-round box ships with non-corrosive Boxer primers seated in reloadable brass cases, allowing handloaders to tune loads for specific rifle chambers.

The 180-grain BondStrike bullet sits at the heavy end of the 300 WSM spectrum, balancing sectional density for penetration with retained velocity for flat trajectory. Handloaders appreciate the uniform case dimensions and flash-hole geometry, which support consistent powder ignition and tight velocity spreads. All 300 WSM ammo requires magazines and actions built for Winchester Short Magnum cartridges—verify chamber compatibility before ordering.
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.
- Follow the four rules of firearm safety at all times — treat every firearm as loaded, never point at anything you’re not willing to destroy, keep your finger off the trigger until ready to fire, know your target and what lies beyond it.
- Verify current ammunition restrictions in your state, county, and municipality — some jurisdictions regulate bullet types, magazine capacities, or shipment methods.
- This ammunition contains lead components. Wash hands after handling, avoid inhaling combustion residue at indoor ranges, and store cartridges in sealed containers away from children and pets. California Proposition 65 warning applies — see manufacturer labeling for details.
