Lee Precision 90231 Quick Trim Die 308 Winchester Case Trimmer

The Lee Precision 90231 Quick Trim Die transforms 308 Winchester case preparation from a tedious multi-step process into a single, precise operation. This specialized trimming die eliminates the need for separate measuring, marking, and cutting steps that traditional case trimming methods require.

What Makes This Different

Unlike conventional case trimmers that require multiple adjustments and measurements, this quick trim die performs chamfering, deburring, and length trimming simultaneously in one press stroke. The integrated cutting mechanism maintains consistent case length within 0.001 inches, while the built-in chamfer tool creates uniform case mouths. This design reduces trimming time by approximately 75% compared to traditional hand-operated trimmers.

Key Features

• Integrated trimming and chamfering system eliminates multiple tool changes
• Precision-ground carbide cutter maintains sharp edge through 5,000+ cases
• Self-centering mandrel ensures consistent case neck alignment
• Compatible with standard 7/8-14 thread reloading presses
• Hardened steel construction with corrosion-resistant finish
• Adjustable cutting depth for custom case length specifications
• Includes replacement cutter and detailed setup instructions

This trimming die excels in high-volume reloading scenarios where consistent case preparation directly impacts accuracy. Match shooters appreciate the uniform case mouth preparation that promotes consistent bullet seating depth. The die handles military surplus brass effectively, removing the crimped primer pocket material while trimming to specification. Weather-resistant construction ensures reliable operation in humid conditions without binding or corrosion issues.
