The Nosler Match Grade .300 Winchester Magnum 210-grain Reduced Drag Factor (RDF) Hollow Point Boat-Tail (HPBT) Brass 20-round box is an elite centerfire rifle cartridge engineered specifically for Extreme Long-Range (ELR) shooting, Precision Rifle Series (PRS) heavy division competition, and 1,000+ yard benchrest matches. A primary performance constraint when shooting heavy-caliber match ammunition at extended ranges is vertical shot dispersion and crosswind deflection caused by irregular bullet meplats and suboptimal aerodynamic drag profiles. Nosler eliminates these downrange inconsistencies through its RDF projectile design, featuring a tightly closed, uniform meplat and an optimized boat-tail profile that maintains supersonic stability well past 1,000 yards.
The primary technical advantage centers on Nosler's heavy 210-grain RDF projectile geometry. Featuring a compound ogive paired with an extended boat-tail angle and a factory-optimized small meplat, the bullet achieves an ultra-high G1 ballistic coefficient of 0.701 (G7 BC: 0.354). This high aerodynamic efficiency minimizes air resistance and crosswind drift while preserving downrange velocity to delay transonic instability. The uniform meplat eliminates the need for bullet tipping or meplat trimming before match competition, while Nosler's match-grade lead-alloy core and concentric jacket yield tight rotational balance.
Launching its heavy 210-grain RDF projectile at a factory-rated 2,750 FPS muzzle velocity (generating 3,526 ft-lbs of muzzle energy), this Match Grade load delivers flat trajectories and predictable elevation adjustments for ELR targets. Assembled in custom-prepped Nosler virgin brass cases—featuring deburred flash holes, uniform primer pockets, and precise neck tension—alongside clean-burning, temperature-stable propellants and non-corrosive match Boxer primers, the cartridge ensures low standard deviations (SD) in velocity, tight chamber sealing, and clean extraction in precision bolt-action magnum rifles.
Key Benefits
- Ultra-High 0.701 G1 Ballistic Coefficient: Heavy RDF profile minimizes drag and wind drift for repeatable impact accuracy beyond 1,000 yards.
- Factory-Optimized Small Meplat: Closed, uniform tip eliminates the need for manual meplat trimming or pointing before matches.
- Nosler Custom Prepped Match Brass: Features deburred flash holes and uniform neck tension to minimize velocity spreads and vertical dispersion.
- Temperature-Stable Propellants: Maintain consistent muzzle velocities and stable point-of-impact across changing environmental conditions.
