RCBS AR Series Small Base 338 Federal Full Length Sizing, Bullet Seating 2 Die Set with Taper Crimp

Overview

The RCBS AR Series Small Base 2-Die Set includes a Small Base Sizer Die and a Taper Crimp Seater Die, designed to ensure reliable feeding and chambering in semi-automatic, pump-action, or lever-action rifles. The Small Base Sizer Die sizes brass to minimum specifications, which is essential for consistent chambering in AR-platform firearms. The Taper Crimp Seater Die is designed to be more forgiving with varying case lengths, helping to reduce shoulder buckling or bulges when crimping bullets with a cannelure. These dies are compatible with any single-stage or turret press that accepts 7/8"-14 threaded dies. Note that consistent use of high-quality lubricant is required for the sizing operation, and shellholders are sold separately.
