The Lee Precision 90881 RGB 2-Die Set delivers precision reloading capabilities for 300 Winchester Magnum cartridges with consistent neck tension and proper case preparation. This RGB (Red, Green, Blue) color-coded system simplifies die identification while maintaining Lee's reputation for reliable performance.

What Makes This Different

The RGB color-coding system eliminates guesswork during die changes, with each die clearly marked for instant identification. Unlike standard die sets that require constant checking, this system reduces setup time by 40% compared to traditional unmarked dies. The hardened steel construction withstands the high pressures associated with magnum cartridge reloading, while the precision-ground surfaces ensure consistent bullet seating depth within 0.002 inches.

Performance testing shows this die set produces ammunition with velocity standard deviations under 15 fps when used with quality components. The full-length sizing die handles fired cases from various chamber dimensions, making it suitable for bolt-action rifles, semi-automatics, and custom chambers.
