The Lee Precision 91018 Collet Neck Die delivers precise neck sizing for 30-30 Winchester cartridges without overworking brass cases. 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, this collet neck die sizes only the case neck while leaving the body untouched. The mandrel-based design prevents excessive brass flow and eliminates the need for case lubrication. This approach reduces work hardening and can extend case life by 50% or more compared to conventional sizing methods.
Key Features
- Collet design sizes neck only, preserving case body dimensions
- Mandrel system eliminates need for sizing lubricant
- Hardened steel construction with precision-machined threads
- Standard 7/8"-14 thread fits most single-stage presses
- Includes sizing mandrel and collet assembly
- Works with both new and fired 30-30 Winchester brass
- Compatible with Lee, RCBS, Hornady, and Dillon presses
This neck die excels in applications where fired cases are chambered in the same rifle repeatedly. Hunters and target shooters benefit from reduced case preparation time and more consistent bullet seating. The gentle sizing action maintains case concentricity while providing uniform neck tension shot after shot.
