The Forster 308 National Match Full-Length Sizing Die (brand part no. 018311) resizes fired 308 brass, machined from a solid one-piece steel reamer for tight, repeatable dimensions. As the National Match version, it bumps the shoulder back roughly 0.003 inch, the setback long favored by High Power/XTC shooters running the M1A/M14 platform. Forster Products builds this die with an elevated (E-Z Out) floating expander ball that keeps the case neck aligned with the body as it clears the die, improving concentricity over a standard expander setup. It’s sold as a single sizing die, so it pairs with a seating die you already own for precision and competition shooting.
