Federal GM205MAR Gold Medal Small Rifle Primers 1000/Box 5000/Case

The Federal GM205MAR Gold Medal Small Rifle Primers deliver match-grade consistency for precision AR-15 builds and bolt-action rifles across multiple calibers. These military-spec primers provide reliable ignition in semi-automatic platforms while maintaining the tight tolerances demanded by competitive shooters. Federal's Gold Medal line represents the company's premium primer technology, engineered for applications where standard primers fall short.

What Makes This Different

Gold Medal primers feature harder cup construction and more sensitive priming compound compared to standard small rifle primers. The GM205MAR designation indicates military-spec hardness ratings that prevent primer flow in high-pressure loads while maintaining consistent ignition across temperature extremes. Federal's manufacturing process ensures primer pocket fit tolerances within 0.001 inches, reducing velocity variations that can open groups at extended ranges.

Key Features

• Military-spec cup hardness prevents primer flow in high-pressure AR loads
• Match-grade consistency with velocity standard deviation under 10 fps
• Compatible with .223 Remington, 5.56 NATO, .308 Winchester, and similar small rifle cartridges
• Temperature-stable compound performs from -40°F to 140°F
• Precise anvil positioning ensures uniform flame distribution
• Bulk packaging of 5,000 primers (5 boxes of 1,000) for high-volume reloaders
• Non-corrosive, non-mercuric formulation prevents barrel damage

Competitive shooters rely on these primers for consistent muzzle velocities that translate to predictable bullet drop at long range. The harder cup construction makes them ideal for semi-automatic rifles where standard primers might back out or pierce under rapid firing conditions. Service rifle competitors particularly value the temperature stability during all-day matches where ambient conditions change significantly. The bulk case quantity serves high-volume reloaders who demand consistent components across thousands of rounds.
