Lee Precision 90823 Factory Crimp Die 308 Winchester 303 Savage

The Lee Precision 90823 Factory Crimp Die delivers consistent bullet seating depth and proper case mouth tension for 308 Winchester and 303 Savage cartridges. This specialized reloading die eliminates inconsistent crimping that can affect accuracy and feeding reliability in bolt-action and semi-automatic rifles.

What Makes This Different

Unlike standard roll crimp dies that can buckle case walls, the Factory Crimp Die uses a collet system that applies uniform radial pressure around the entire case mouth. This approach maintains consistent neck tension while preventing case damage that shortens brass life. The die works with both cannelured and non-cannelured bullets, providing versatility across different projectile types.

Key Features

• Collet-style crimping system applies even pressure without case wall deformation
• Compatible with both 308 Winchester and 303 Savage cartridges
• Works with cannelured and smooth bullets up to 180 grain weight
• Standard 7/8"-14 threading fits most single-stage and turret presses
• Hardened steel construction with corrosion-resistant finish
• Includes detailed setup instructions and load data references
• Produces factory-specification cartridge overall length consistency

Reloaders report improved feeding reliability in AR-10 platforms and bolt-action rifles when using this crimp die as the final step in their reloading process. The consistent neck tension helps maintain uniform powder burn rates, contributing to tighter group sizes at extended ranges. Military surplus brass benefits particularly from the controlled crimping action, which can extend case life by 20-30% compared to aggressive roll crimping methods.
