Lee Precision 90958 Collet Die 270 Winchester Reloading Die

The Lee Precision 90958 Collet Die delivers precise neck sizing for 270 Winchester cases without overworking the brass. This specialized reloading die extends case life while maintaining consistent neck tension for improved accuracy.

What Makes This Different

Unlike traditional full-length sizing dies that resize the entire case, this collet die focuses exclusively on neck sizing. The mandrel-based design prevents excessive brass flow and maintains proper case dimensions. Cases sized with this die typically last 30-50% longer than those processed through conventional full-length dies, reducing reloading costs over time.

Key Features

• Precision-machined collet system for consistent neck tension
• Mandrel design prevents case neck splitting and overworking
• Compatible with standard 7/8"-14 thread press systems
• Hardened steel construction for long-term durability
• Requires minimal case preparation and trimming
• Works with both new and fired 270 Winchester brass
• Includes detailed setup and adjustment instructions

This collet die excels in precision rifle applications where accuracy consistency matters most. Match shooters and hunters benefit from the improved concentricity and reduced runout that collet sizing provides. The gentle sizing action preserves case neck integrity, making it ideal for premium brass that costs $1+ per case. Cold weather performance remains consistent since the collet mechanism operates smoothly regardless of temperature.
