Hornady 046052 Custom Grade Series IV Neck Sizer Die 6mm PPC

The Hornady 046052 Custom Grade Series IV Neck Sizer Die delivers precision neck sizing for 6mm PPC cartridges without disturbing the case body or shoulder. This specialized die maintains optimal case life while ensuring consistent neck tension for match-grade accuracy.

What Makes This Different

The Series IV design incorporates Hornady's floating alignment system that self-centers cases during the sizing operation. Unlike full-length sizing dies that work the entire case, this neck sizer only reduces the case neck diameter by approximately 0.002-0.003 inches. The precision-ground steel construction maintains tolerances within 0.0005 inches for consistent results across thousands of reloading cycles.

Key Features

• Neck-only sizing preserves case body dimensions and extends brass life
• Floating alignment system prevents case damage during operation
• Precision-ground steel construction with heat-treated surfaces
• Standard 7/8-14 threads fit all major reloading presses
• Includes lock ring and detailed reloading instructions
• Reduces neck diameter by 0.002-0.003 inches for optimal bullet grip
• Compatible with 6mm PPC brass from all manufacturers

This die excels in competitive shooting scenarios where maximum accuracy matters most. Cases sized with neck-only dies typically show 30-50% longer life compared to full-length sizing, making it economical for high-volume shooters. The consistent neck tension produces uniform bullet release, critical for benchrest and long-range precision shooting where groups under 0.25 MOA separate winners from also-rans.
