The RCBS MatchMaster Competition Seating Die in .260 Remington (RCBS part no. 12840) is a stand-alone seater built for handloaders who chase precision. RCBS machines the die from case hardened steel and finishes it in a deep blued finish. A bullet seating window lets you drop the bullet in and run the press, and an internal sleeve holds the bullet in line with the case. The oversized micrometer adjustment lets you dial seating depth in thousandths of an inch.
