What Makes This Different

Lyman's Pro Die series features hardened steel construction with precision-ground surfaces that maintain tighter tolerances than standard reloading dies. The sizing die includes an expander ball that's perfectly centered for uniform case neck tension. Each die undergoes quality control testing to ensure dimensional accuracy within 0.001 inches, resulting in ammunition that chambers smoothly and shoots consistently.
