RCBS MATCHMASTER COMP SEAT DIE 308WIN Matchmaster dies are the pinnacle of reloading dies with rich features, outstanding fit and finish, and unbeatable accuracy. Available in both full-length size and neck-size sets, as well as a stand-alone seater die, you will enjoy years of use from Matchmaster dies. Each die is made from case hardened steel, the inside surfaces are precision-drilled and reamed to exacting standards, and hand polished. The Matchmaster seater die is beautifully machined, polished, and finished off with a deep blued finish like on the finest firearms. The large, oversized adjustment knob on the Matchmaster seater die has oversized letters and hash marks making it both precise to turn as well as easy to read. Dial one thousandth of an inch, and that is exactly what you will get. The seater also features our exclusive loading window which allows you to drop the bullet in and simply run the press to seat your bullet. No more trying to balance a bullet on a case mouth or putting fingers in danger. The internal sleeve catches and holds the bullet in perfect alignment with the case and guides it during the seating operation for astoundingly concentric results.
