Nosler Trophy Grade 300wm 180g - 20rd 10bx/cs Partition

The Nosler Trophy Grade 300 Winchester Magnum 180 grain Partition ammunition is purpose-built for hunters and precision rifle shooters who demand consistent, ethical terminal performance on medium to large game. This cartridge combines Nosler's legendary Partition bullet technology with quality brass and reliable primers, making it a go-to choice for both guided hunts and personal shooting disciplines where shot placement and energy transfer are non-negotiable.

The 180 grain Partition projectile features Nosler's proprietary dual-core design: a soft, lead front section that expands reliably upon impact, and a heavy, bonded rear core that retains mass and drives deep for controlled penetration. This architecture minimizes bullet fragmentation and maximizes energy dump in vital zones, delivering the kind of one-shot stops that separate quality ammunition from budget alternatives. The .300 WM cartridge itself delivers flat trajectories and retained energy beyond 400 yards, making it effective across varied hunting distances and conditions without requiring extreme hold-over adjustments.

Serious .300 Winchester Magnum rifle owners—whether using Model 700s, Model 70s, custom builds, or other bolt actions chambered in this cartridge—will find this ammunition reliable for elk, moose, bear, and long-range precision applications. The 20-round box format allows for practical stock rotation and field use without overcommitting to bulk purchases. Store in a cool, dry environment and verify chamber fit and velocity in your specific rifle before hunting or competition use to ensure consistent ballistic data.
