Hornady Series III 2-Die Set .338 ARC - Full Length Sizing Dies

The Hornady Series III 2-Die Set for .338 ARC delivers precision reloading capabilities for this modern cartridge designed for AR-15 platforms. This professional-grade die set enables consistent ammunition production with the dimensional accuracy required for optimal performance in gas-operated systems.

What Makes This Different

Series III dies incorporate Hornady's advanced manufacturing tolerances and hardened steel construction that exceeds SAAMI specifications. The full-length sizing die features an elliptical expander that reduces case neck tension variations by 50% compared to standard round expanders. Internal geometry matches .338 ARC chamber specifications precisely, ensuring proper headspace and consistent case preparation for both bolt-action and semi-automatic platforms.

Key Features

• Full-length sizing die with integrated decapping pin for complete case preparation
• Bullet seating die with built-in crimp ring for consistent bullet depth and secure retention
• Elliptical expander reduces neck tension variation and extends case life
• Hardened steel construction with corrosion-resistant finish
• 7/8-14 threading compatible with all standard reloading presses
• Includes detailed setup instructions and load data references
• Zip-Spindle design allows quick die adjustments without losing settings

Field testing demonstrates consistent case dimensions within 0.001" across multiple reloading cycles. The sizing die handles both new and fired brass effectively, returning cases to SAAMI minimum dimensions while maintaining structural integrity. Bullet seating remains uniform shot-to-shot, critical for maintaining accuracy in precision rifle applications and reliable feeding in semi-automatic systems.
