RCBS MATCHMASTER – NECK SIZE BUSHING DIE SET .300 Win Mag

RCBS MATCHMASTER – NECK SIZE BUSHING DIE SET .300 Winchester Magnum

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. 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.

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.

Each die is made from case hardened steel, the inside surfaces are precision-drilled and reamed to exacting standards, and hand polished.

Matchmaster sizing dies use interchangeable neck bushings with changeable diameter.
