Lee Precision 90720 Collet 2-Die Set 7mm Remington Magnum

The Lee Precision 90720 Collet 2-Die Set delivers precision neck sizing and bullet seating for 7mm Remington Magnum cartridges. This two-die system maintains case concentricity while extending brass life through minimal shoulder movement during the resizing process.

What Makes This Different

The collet neck sizing die reduces case working compared to full-length sizing dies, preserving brass integrity for up to 15-20 reloads per case. The mandrel-style design centers bullets consistently during seating, improving concentricity by 50% over standard expander ball systems. Factory crimp die provides uniform bullet retention without over-crimping that can affect accuracy.

Key Features

• Collet neck sizing die extends brass life and maintains case concentricity
