Redding Competition 257 Roberts Ackley Improved 40-Degree Shoulder Bushing Neck Sizing Die

Overview

The Redding Competition Bushing Neck Sizing Die is designed for the .257 Roberts Ackley Improved cartridge. It features a design that completely supports and aligns the cartridge case with the sizing bushing before the sizing process begins. As the case is moved upward, it remains supported in a tightly chambered, sliding sleeve while the resizing bushing self-centers on the neck. The die uses the internal components as a linear support for the decapping rod to maintain precise alignment. A micrometer adjustment allows for fine-tuned control over the length of the neck being sized. Please note that bushings and shellholders are sold separately.
