Precision expanding mandrel die for 6mm brass preparation. Stainless steel construction with interchangeable mandrels, cut-out viewing window, and L.E. Wilson lock nut. Made in USA.
The L.E. Wilson Expanding Mandrel Die is an essential tool for serious reloaders who demand precision and consistency. This die prepares brass cases for optimal bullet seating by expanding the neck to slightly under bullet diameter, ensuring uniform neck tension and consistent seating depth across all your rounds.
New brass often arrives with inconsistent neck dimensions, particularly after bulk shipping. This die ensures every case is properly prepared for its first firing. By establishing uniform neck tension, you'll achieve more consistent velocities and tighter shot groups—the hallmark of precision reloading.
One mandrel sized for 6mm (.242") is included. Additional mandrels for other calibers are available separately, making this a versatile addition to your reloading bench.
Whether you're loading for competition or hunting, the L.E. Wilson Expanding Mandrel Die delivers the precision control serious reloaders expect.
