Product Description The RCBS Neck Sizer Die Group A for .308 Winchester is a precision reloading die set engineered specifically for bottleneck cases fired in bolt-action rifles. Designed for reloaders who fire cases from a single rifle and reload them for that same firearm, this die set sizes only the neck of the cartridge - leaving the shoulder and body untouched - for a close, custom-fit chamber-to-case relationship that maximizes accuracy and brass longevity. The set includes a Neck Sizer Die with an Expander-Decapping Unit, which resizes the case neck and de-primes the spent primer in one pass, and a Seater Die with a Bullet Seater Plug featuring a built-in roll crimper that seats the bullet and secures it simultaneously. The dies are compatible with all standard 7/8-14 threaded reloading presses and are packaged in an RCBS plastic die box for storage and protection. Product Highlights Neck-Only Sizing: Resizes only the case neck without touching the shoulder or body, preserving brass life and maintaining a tight chamber-to-case fit for improved accuracy in bolt-action rifles. Expander-Decapping Unit Included: The Neck Sizer Die comes with an Expander-Decapping Unit that decaps spent primers while ensuring proper bullet tension after sizing. Built-In Roll Crimper: The included Seater Die features a built-in roll crimper, allowing the bullet to be seated and crimped in a single, efficient step. Universal Press Compatibility: Fits all standard 7/8-14 threaded reloading presses, making it a versatile addition to any reloading setup. Purpose-Built for .308 Winchester: Optimized for .308 Win / 7.62 NATO cartridges, this Group A die set delivers consistent, repeatable results for competitive and precision shooters alike.
