Hornady 390751 Large Primer Pocket Reamer Multi-Caliber Steel Tool

The Hornady 390751 Primer Reamer delivers precision primer pocket maintenance for large rifle and pistol cases across multiple calibers. This essential reloading tool removes carbon buildup and restores proper primer seating depth for consistent ignition and improved accuracy.

What Makes This Different

Unlike generic pocket cleaners, this reamer features precisely machined cutting edges that remove material uniformly without over-cutting. The hardened steel construction maintains sharp edges through thousands of primer pockets. The multi-caliber design eliminates the need for separate tools across different cartridge families, making it more efficient than single-purpose alternatives.

Key Features

• Large primer pocket compatibility for rifle and pistol cartridges
• Hardened steel construction resists wear and maintains cutting edge geometry
• Multi-caliber design works with .308, .30-06, .45 ACP, and other large primer cases
• Precision-ground cutting surfaces ensure uniform material removal
• Compact profile allows easy handling and storage in reloading bench setups
• Silver finish provides corrosion resistance in humid environments
• Compatible with standard reloading press setups and hand-held operation

This reamer excels in high-volume reloading scenarios where primer pocket maintenance becomes critical for consistent performance. Competition shooters rely on uniform primer seating for shot-to-shot consistency, while hunters benefit from reliable ignition in temperature extremes. The tool handles both once-fired brass and cases with multiple reload cycles, extending case life by maintaining proper pocket dimensions.
