This two-die set from RCBS is designed for reloading bottleneck cases used in tight-chambering semi-automatic, pump, or lever-action rifles. It pairs a Small Base Sizer with an Expander-Decapping Unit and a Regular Seater Die with Seater Plug to provide resizing, depriming, and bullet seating functions. The seater die includes a roll crimper to secure the bullet during use, and the seater can be adjusted to seat without crimping if desired.
