Lyman MSR Precision Die System 4-Die Set .458 SOCOM Bushmaster 7690110

The Lyman MSR Die Set is specifically designed for reloaders looking to fine-tune loads for their AR-style modern sporting rifle. The dies are loaded with MSR-specific features, ensuring that MSR-owning handloaders can tailor their handmade rounds for their semi-automatic, magazine-fed rifle systems.

The Lyman MSR Die Set ships with an included Small Base Sizing Die, which works to resize MSR cartridges to a slightly smaller than standard size in order to promote smooth, trouble-free feeding from the magazine into the chamber. The dies also feature a specially- designed Taper Crimp Die that gives cases an extra-strong crimp in order to preserve overall cartridge length when feeding from a magazine.

• Ammo Checker cartridge "Go" gauge included with each set
• Available for .223 Rem. and .450 Bushmaster.
• Comes with clear, plastic storage case
• Features black finish

The Lyman MSR Die Set also ships with Lyman's Ammo Checker gauge, enabling users to safety-check their loaded rounds for consistency.
