RCBS MatchMaster 280 Ackley Improved Bullet Seating Die

This is the MatchMaster bullet seating die for 280 Ackley Improved. The adjustment knob on top is oversized, with large letters and hash marks that can be read without squinting, and it dials in one thousandth of an inch increments - ask for a thousandth and that is what you get.

The loading window is the other feature worth knowing: drop the bullet into the side of the die, run the press, and the bullet seats without balancing it on a case mouth first. The die itself is machined, polished and finished with a deep blued finish. 280 Ackley Improved is a handloader's cartridge, and a seating die that repeats to the thousandth is the kind of tool it attracts.
