Redding Neck Die Set for Bottleneck Cases .20 Nosler

The Redding Neck Die Set for Bottleneck Cases .20 Nosler is a precision reloading tool designed for shooters working with the .20 Nosler cartridge. This two-die set provides the essential components needed to resize and seat ammunition with the consistency and accuracy that modern match-grade reloading demands. The .20 Nosler represents a popular choice among precision rifle shooters who value the balance of flat trajectory, minimal wind deflection, and effective range across varied hunting and target applications.

The set includes two precision dies: a neck resizing die containing a decapping rod assembly with integrated neck expander (size button), and a seating die featuring a built-in bullet guide, crimp ring, and proper seating plug. This configuration allows you to remove spent primers and resize the neck in the first operation, then seat bullets and establish crimp in the second stage. For bottleneck cases like the .20 Nosler, proper neck sizing is critical to ensuring consistent bullet fit and concentricity. The included expander button controls case neck interior diameter after sizing, directly influencing bullet-to-case tension and shot-to-shot velocity uniformity—key factors in achieving repeatable accuracy at distance.

This die set serves precision rifle reloaders, long-range hunters, and competitors who shoot .20 Nosler and require tight quality control over their ammunition. The .20 Nosler die set is compatible with standard single-stage and progressive reloading presses that accept standard die threading. Redding reloading equipment is recognized among serious handloaders for tight manufacturing tolerances and reliable performance. The product weighs 1.29 lbs and fits standard reloading bench space.
