Die Cal. 375 H&H LEE Reloading Dies

Lee 3-Die Set for .375 H&H Magnum Caliber

This comprehensive three-die kit, crafted from high-grade steel, is specifically engineered for precision reloading of the .375 H&H Magnum cartridge, a staple in big game hunting and dangerous game defense.

The set includes the following dies:

1. Full-Length Resizing Die: This die is designed to recalibrate the brass case by removing the spent primer and slightly expanding the neck to ensure consistent chambering and optimal bullet seating. Proper resizing is critical to maintain case integrity and ensure reliable cycling in bolt-action and semi-automatic rifles.

2. Bullet Seating Die: This adjustable die allows for precise control over bullet seating depth, enabling reloaders to set the projectile at the exact depth required for optimal ballistic performance and pressure management. It also initiates the case neck crimp, but caution is advised to avoid excessive crimping, which can deform the case neck into a rolled shape and potentially damage the brass.

3. Factory Crimp Die: For applications requiring a robust and consistent crimp—particularly when loading cartridges for lever-action or semi-automatic firearms—this die provides a strong, uniform crimp without compromising case integrity. Utilizing this die ensures reliable feeding and ignition under high-stress hunting or tactical conditions.

Additional components included in the kit:

Shell Holder: Designed to securely hold the .375 H&H Magnum case during the resizing and seating operations, ensuring precise alignment and repeatability on your reloading press.

Powder Measure Tool: A calibrated powder scoop for accurate measurement of propellant charges, essential for maintaining consistent muzzle velocities and safe pressure levels.

Loading Data Chart: A detailed, non-Spanish powder load table tailored for the .375 H&H Magnum, providing recommended charge weights, velocities, and pressure limits for various powders commonly used in metallic and semi-metallic cartridge reloading.

Important Note: It is essential to lubricate the brass cases thoroughly before resizing to prevent case sticking and ensure smooth die operation, thereby extending the lifespan of both your brass and dies.

This Lee 3-Die Set is an indispensable tool for precision handloaders seeking to maximize the performance, reliability, and safety of their .375 H&H Magnum ammunition, whether for professional hunting, competitive shooting, or ballistic experimentation.
