RCBS 15530 Neck Sizer Die Group A 308 Win

The RCBS 15530 Neck Sizer Die is a two-die set from the popular Group A series, purpose-built for .308 Winchester bottleneck cases used in bolt-action rifles.

The Neck Sizer Die features an integrated Expander-Decapping Unit that resizes only the case neck without disturbing the shoulder or body, while simultaneously de-priming spent cases. The included Seater Die is paired with a matching bullet seater plug for seating projectiles to your chosen overall length. Both dies use standard 7/8x14 threads for compatibility with virtually any standard single-stage or progressive reloading press.

Neck-only sizing preserves the fire-formed shoulder geometry of each case, allowing reloaders chasing tight groups to maintain proper case fit while refreshing neck tension around the bullet. Made in the USA and backed by RCBS's reputation for precision reloading tooling, this set is a focused solution for the .308 Win handloader prioritizing consistent neck sizing and accuracy.
