Federal GM210M Gold Medal Large Rifle Magnum Primers - 1000 Count

The Federal GM210M Gold Medal Large Rifle Magnum Primers deliver the consistent ignition performance that precision shooters and reloaders demand for magnum cartridges. These match-grade primers feature Federal's advanced priming compound formulation, engineered specifically for reliable ignition of slow-burning powders in large rifle magnum applications.

What Makes This Different

Federal's Gold Medal primer line represents the pinnacle of primer manufacturing technology, utilizing stricter quality control standards than standard primers. The GM210M features a hotter, more consistent flame compared to standard large rifle primers, ensuring complete powder ignition even with temperature-sensitive magnum loads. Each primer undergoes individual inspection for dimensional consistency and priming compound uniformity, resulting in shot-to-shot velocity variations typically under 10 fps.

Key Features

• Match-grade large rifle magnum primers optimized for precision reloading
• Enhanced priming compound delivers consistent ignition across temperature ranges
• Individual quality inspection ensures dimensional uniformity within 0.001 inches
• Compatible with magnum rifle cartridges including .300 Win Mag, 7mm Rem Mag, .338 Lapua
• Sealed construction provides moisture resistance for long-term storage
• Brass cup construction withstands high-pressure magnum cartridge loads
• 1000-count packaging reduces cost per round for high-volume reloaders

These primers excel in competitive long-range shooting applications where consistent velocities translate directly to improved accuracy downrange. The GM210M's reliable ignition characteristics make them particularly suitable for temperature-extreme hunting conditions and precision rifle competitions. Benchrest shooters frequently choose Gold Medal primers for their ability to maintain consistent performance across varying atmospheric conditions, while the magnum formulation ensures complete powder burn in large-capacity cartridge cases.
