Lee Precision Quick Trim Rifle Die .300 H&H/Ultra

The Lee Precision Quick Trim Rifle Die .300 H&H/Ultra is a precision brass case trimmer die engineered specifically for handloaders working with magnum rifle cartridges. Designed to integrate seamlessly with Lee's Deluxe Quick Trim or Value Quick Trim Case Trimmer systems, this die holds rifle brass securely during the trimming process, ensuring consistent case length specifications essential for accurate ammunition reloading. Brass case trimming is a critical step in the handload sequence—improper case length directly affects cartridge headspace, powder charge accuracy, and chamber fit, making a quality trimming die indispensable for serious reloaders.

The .300 H&H/Ultra specification indicates this die is calibrated for the .300 Holland & Holland Magnum and .300 Ultra Magnum cartridges—heavy-hitting rifle rounds used in long-range hunting and precision rifle applications where ammunition consistency directly impacts ballistic performance. Lee's Quick Trim system operates with a cutter that automatically adjusts to trim each case to SAAMI-specification length, eliminating the need for manual adjustment between cases. The die's construction provides repeatable, precision fit within the trimmer collet, critical for magnum cartridges where case wall thickness and capacity variations are more pronounced than in standard rifle rounds.

This die serves reloaders who demand precision in their handload process—hunters preparing custom ammunition for big-game hunting, long-range precision shooters, and competitive riflemen who reload magnum cartridges in volume. The compatibility with Lee's established Quick Trim platform makes this die a practical upgrade or replacement component for reloaders already invested in that system. At 0.38 lbs, the die integrates efficiently into an organized reloading bench setup without requiring additional space or standalone equipment.
