Lyman300 Winchester Mag Carbide Neck Size Die Only
The Lyman300 Winchester Mag Carbide Neck Size Die is engineered for precision neck sizing of .300 Winchester Magnum bottleneck cases, catering to discerning reloaders seeking enhanced accuracy and case longevity. Designed for those who reload rifle cartridges for target shooting, hunting, or competition, this die offers consistent neck tension while minimizing case stretching. Its specialized construction makes it ideal for reloaders who prefer neck sizing to maximize the performance and lifespan of their brass.
Product Overview
This Lyman neck size die features a hardened, CNC-machined steel body for durability and dimensional consistency. The integrated carbide expander button is exceptionally hard and provides a smooth, low-friction surface, reducing wear on both the die and the brass. The expander button is free-floating and self-centering, ensuring uniform neck expansion and concentricity with each use. Designed with standard 7/8x14 threads, this die is compatible with virtually all popular single-stage and turret reloading presses. By sizing only the neck of the case, it reduces unnecessary working of the brass, which helps to prolong case life and maintain optimal chamber fit for improved accuracy.
