Lyman MSR Precision Die System 4-Die Set 50 Beowulf

The Lyman MSR Precision Die System is purpose-built for handloading the 50 Beowulf cartridge - the powerful, straight-walled round developed by Bill Alexander of Alexander Arms for the AR-15 platform. Lyman's MSR die sets are the only sets engineered specifically for Modern Sporting Rifle ammo and are a must for any reloader turning out precise, reliable rounds in this hard-hitting caliber.

This 4-die set is precision machined from high-grade steel and includes a small base sizing die for tight, consistent case sizing, Lyman's signature "M" Neck Expanding Die optimized for straight-walled cases, and a taper crimp die that delivers added bullet grip for smooth functioning through semi-auto actions. Together, the four dies provide a complete reloading solution calibrated to factory-spec 50 Beowulf dimensions.

Whether loading for a dedicated 50 Beowulf AR or expanding a multi-caliber reloading bench, the MSR Precision Die System pairs with any standard reloading press to produce consistent, accurate ammunition. Lyman delivers the precision and reliability reloaders expect from a purpose-built die set.
