The RCBS Matchmaster Competition Seating Die for .308 Winchester (RCBS part no. 15540) combines the best features of RCBS’s Gold Medal and Competition series seating dies into one product. Like the rest of the Matchmaster line, it uses an oversized micrometer adjustment with large, easy-to-read markings for repeatable seating depth. An exclusive loading window lets you drop a bullet in and run the press instead of balancing it on the case mouth by hand, and a free-floating, self-centering seating stem keeps bullets concentric with the case. It’s built for .308 Winchester shooters who want genuine competition-grade seating precision.
