RCBS 24040 MatchMaster Micrometer Adjustable Seating Die - 7/8"-14 Thread

The RCBS 24040 MatchMaster micrometer adjustable seating die is purpose-built for precision handloaders who demand repeatable, exact bullet seating. Part of RCBS's flagship MatchMaster line, the 24040 brings decades of reloading engineering to a single die body cut with the standard 7/8x14 thread pattern that drops into virtually any standard reloading press.

The oversized micrometer adjustment knob lets you dial bullet seating depth in precise, repeatable increments so you can fine-tune cartridge overall length for match-grade accuracy. A free-floating, self-centering bullet seating stem centers the bullet against the case mouth without flexing or misalignment, while the large loading window gives you a clear view of the bullet as it seats for at-the-bench confirmation.

Standard 7/8x14 threads make the RCBS 24040 compatible with the broad majority of common reloading presses. Built in the USA and backed by RCBS's limited lifetime warranty, the die ships in its own protective storage box. A shellholder is sold separately.
