Hornady Custom Grade Series I 2-Die Set for .303 British (Includes Sizing & Seater) - 546366

The Hornady Custom Grade Series I 2-Die Set for .303 British gives you everything needed to reload this classic rifle cartridge with precision and confidence. Built for shooters who handload for older or less common calibers, this two-die set pairs a full-length sizing die with a bullet seater die—the essential tools for consistent, accurate rounds. Hornady's Custom Grade dies are known for tight tolerances and a smooth internal finish that'll serve you reliably for decades.

The sizing die features Hornady's Zip Spindle design, which locks securely to eliminate slippage during the sizing stroke. Fine threads cut into both the spindle and spindle collet let you make small, repeatable adjustments by turning the spindle, or zip up and down quickly for larger changes. The seater die includes an in-line bullet seating system with a built-in crimper and adjustment screw retainer ring, giving you control over bullet depth and crimp in a single stroke. Both dies ship in easy-access boxes for organized storage in your reloading bench.

If you're loading for a .303 British rifle—whether a vintage Lee-Enfield, a modern sporter, or a project gun—this set handles the job without fuss. Hornady stands behind these dies with a lifetime warranty against breakage or wear from normal use, so you can reload with the confidence that comes from proven, American-made equipment.
