Lee Full Length 3-die Set - .300 H&h Magnum

The Lee Full Length 3-die Set for .300 H&H Magnum (SKU 90560) is a precision reloading system purpose-built for handloaders working with one of the most respected magnum rifle cartridges ever developed. Whether you're precision rifle shooters, hunters pushing extended-range performance, or competitive shooters demanding consistent ammunition, this three-die set provides the essential tools to produce match-grade rounds tailored to your specific rifle. The .300 H&H Magnum remains a benchmark cartridge for accuracy and power, and reload quality directly determines whether you're maximizing your rifle's potential or leaving performance on the table.

This set includes a full-length sizing die that restores fired brass to factory dimensions for reliable chamber fit across multiple rifles, a precision bullet seating die that controls both depth and runout for consistent ballistics, and a factory crimp die that applies controlled pressure to lock bullets in place without over-crushing the case neck. The included universal shell holder accommodates your press, while the powder dipper enables consistent charge volumes and the included load data ensures safe, optimized loads from trusted sources. Full-length sizing is critical for magnum work where pressure curves are steep and case stretch directly impacts chambering reliability and velocity consistency shot-to-shot.

Handloaders reloading for .300 H&H Magnum bolt-action rifles—from classic Model 70s to modern custom builds—will find this set essential for achieving sub-MOA precision at distance. The three-die configuration supports both new brass preparation and ongoing case maintenance across multiple loadings, making it economical for shooters processing dozens of rounds monthly. Installation integrates into any standard single-stage or progressive press, and the compact dimensions (4.75 x 1.55 x 4.85 inches) fit efficiently on benches with limited space. Lee's reputation for quality control ensures die tolerances that produce concentric ammunition ready for the field or competition range.
