What Makes This Different

Hornady's Match Grade dies feature tighter manufacturing tolerances than standard reloading dies, with bore dimensions held to ±0.0005 inches. The sizing die includes an elliptical expander that reduces case neck runout by 50% compared to conventional ball expanders. Each die undergoes individual inspection and testing before leaving the factory, ensuring consistent performance across the entire production run.

Key Features

Match-grade ammunition requires consistent case preparation and bullet seating depth control. The micrometer seating die allows adjustments in 0.001-inch increments, enabling precise overall length tuning for different bullet weights and profiles. Long-range shooters achieve improved accuracy when cases maintain uniform neck tension and minimal runout. The sizing die's polished interior and vented design prevents case sticking while maintaining proper headspace dimensions.
