The RCBS 32930 is characterized by its distinct Neck Sizer Die which incorporates an Expander-Decapping Unit. It has been designed to resize only the case neck while leaving the shoulder and body untouched. Additionally, it features a de-prime function. In terms of performance, the Neck Sizer Dies are made to only adjust the case neck for a snug fit around the bullet, while ignoring any changes to the shoulder or body. Noteworthily, each RCBS Die undergoes a process of hardening and careful hand-polishing. The RCBS finishing technique lends the dies a durable build, allowing them to endure extensive wear caused by abrasive case sizing over many years.
