The Lee Precision 90825 Factory Crimp Die delivers consistent bullet seating and case mouth crimping for 300 Winchester Magnum cartridges. This specialized reloading die addresses the critical final step in ammunition preparation, ensuring uniform cartridge overall length and proper bullet retention for reliable feeding and accuracy.
What Makes This Different
The Factory Crimp Die combines bullet seating and crimping operations in a single step, unlike traditional seating dies that require separate crimping adjustments. The collet-style crimp mechanism applies uniform pressure around the entire case mouth circumference rather than just four points like roll crimp dies. This design maintains consistent neck tension while preventing case mouth deformation that can affect chambering and accuracy.
Key Features
- Collet-style crimp applies uniform 360-degree pressure for consistent neck tension
- Combines bullet seating and crimping operations in single die
- Hardened steel construction with precision-machined threads
- Accepts standard 7/8-14 thread reloading presses

- Compatible with all 300 Winchester Magnum bullet weights and styles
- Eliminates need for separate taper crimp or roll crimp dies
Bench rest shooters and hunters report improved accuracy consistency when using Factory Crimp Dies due to the uniform bullet seating depth and neck tension achieved. The die maintains proper case mouth geometry essential for reliable feeding in bolt-action and semi-automatic rifles chambered in 300 Winchester Magnum. Temperature variations and extended storage periods have minimal effect on cartridges processed with this crimping system.
