Redding Series A Neck Sizing Die for Bottleneck Cases .308 Win/.307 Win

The Redding Series A Neck Sizing Die for Bottleneck Cases .308 Win/.307 Win (part number 81155) is a precision reloading die engineered for shooters who demand consistent case neck preparation. This neck resizing die contains a decapping rod assembly with a neck expander button, allowing reloaders to resize case necks to exact specifications while simultaneously removing spent primers in a single stroke—a critical step in producing match-grade ammunition for precision rifle applications.

Redding manufactures this die from fine alloy steels machined on Hardinge Super-Precision lathes, which ensures tight tolerances and repeatable performance across thousands of reloading cycles. The Series A designation reflects Redding's commitment to quality at an efficient production cost—these dies meet the same exacting standards as Redding's premium lines but benefit from streamlined manufacturing. For .308 Winchester and .307 Winchester bottleneck cases, proper neck sizing is essential to prevent case separation, ensure consistent bullet tension, and maintain the headspace specifications critical to safe, accurate fire.

This die is designed for reloaders who work with .308 Winchester ammunition—whether for precision rifle competition, long-range hunting, or military-spec training loads. Handloaders preparing ammunition for AR-10 platforms, bolt-action precision rifles, or any .308-based cartridge will find this Redding neck sizing die an industry-standard choice. The integrated decapping function reduces setup time and die count required on a progressive or single-stage press, making it a practical addition to any serious reloading bench focused on centerfire rifle ammunition.
