The Lyman 338 Lapua Mag Die Set (Model: LY-338 / LY-338LM) is a precision-engineered reloading tool designed for Australian long-range shooters, competitive marksmen, and hunters who demand absolute consistency from their ammunition. Developed by Lyman, a trusted name in ammunition reloading and case preparation, this die set allows reloaders to process spent .338 Lapua Magnum cartridge cases with extreme accuracy. By resizing fired brass to factory-standard dimensions and ensuring precise bullet seating, this die set helps eliminate variations that can affect downrange accuracy. Whether preparing rounds for extreme long-range target shooting or large-game hunting in the Australian outback, this mechanical die set provides the structural integrity and precision required to produce high-quality handloads.

Key Features:

• Caliber Specificity: Engineered precisely for the .338 Lapua Magnum cartridge, ensuring exact tolerance matching for both resizing and seating steps.
• Robust Steel Construction: Manufactured from hardened steel to resist wear and maintain critical dimensional tolerances over thousands of reloading cycles.
• Standard Thread Compatibility: Uses the industry-standard 7/8-inch by 14 threads per inch (7/8"-14) pattern, making it compatible with almost all standard single-stage and turret reloading presses.
• Two-Die Configuration: Includes a full-length sizing die to return brass to SAAMI-compliant dimensions and a bullet seating die for precise depth adjustment.
• Enhanced Case Life: Smooth internal finishes reduce friction and minimize stretching, extending the reloadable lifespan of expensive .338 Lapua Mag brass cases.
• System Integration: Works seamlessly with other Lyman .338 caliber reloading tools, including the Lyman Single Caliber Ammo Checker, the Lyman Case Trimmer Pilot (.338 diameter), and the Lyman Case Length/Headspace Gauge.
