Hornady 546551 Custom Grade Series II 3-Die Set 444 Marlin

The Hornady Custom Grade Series II 3-Die Set delivers precision reloading capabilities specifically engineered for the 444 Marlin cartridge. This complete die set provides handloaders with the essential tools needed to produce consistent, accurate ammunition that maximizes the performance potential of the powerful 444 Marlin round.

What Makes This Different

Hornady's Custom Grade Series II dies feature heat-treated steel construction with precision-machined tolerances that exceed industry standards. The elliptical expander reduces case neck tension variations by up to 25% compared to standard ball expanders. Each die undergoes individual inspection and hand-polishing to ensure dimensional consistency across the entire production run.

Key Features

• Full-length sizing die with titanium nitride coating for extended service life
• Bullet seating die with built-in roll crimp for secure bullet retention
• Elliptical expander die minimizes case neck working and extends brass life
• Heat-treated steel construction maintains dimensional stability under high pressures
• Precision-ground surfaces ensure consistent cartridge overall length
• Compatible with all standard 7/8"-14 thread reloading presses
• Includes detailed loading data and setup instructions

The 444 Marlin's substantial case capacity and heavy bullet weights demand precise die tolerances to achieve optimal performance. This die set maintains neck tension consistency that translates directly to improved accuracy downrange. The full-length sizing capability ensures reliable chambering in lever-action rifles, while the controlled expansion process preserves case integrity through multiple reloading cycles.
