RCBS 24040 MATCHMASTER MICROMETER ADJ SEATING DIE
$124.11
The RCBS 24040 Matchmaster micrometer adjustment seating die brings precision and safety to your reloading bench. Built for shooters who demand consistency shot after shot, this bullet seating die combines RCBS's reputation for American-made quality with features that make the critical job of seating bullets both easier and more reliable. Whether you're loading for match competition, hunting, or long-range shooting, the Matchmaster delivers the concentricity and repeatability serious reloaders expect.
The standout feature here is the loading window with built-in bullet retention system—a genuine quality-of-life upgrade. Instead of balancing bullets on case mouths or risking your fingers during the seating stroke, the internal sleeve catches and holds the bullet in perfect alignment while the free-floating, self-centering stem guides it true. That means better concentricity in every round and fewer fumbles at the press. The large oversized micrometer knob with legible hash marks and letters lets you dial in precise adjustments—down to one-thousandth of an inch—and actually see what you're doing. The deep blued finish and polished machining aren't just for show; they signal the kind of attention to detail you want in a die that'll outlast most of your firearms.
Built to the standard 7/8"-14 thread, it fits your existing RCBS press setup without fuss. This is the seating die alone—pair it with your sizing die, primer feeder, and other components to complete your reloading line. RCBS backs it with their Limited Lifetime Warranty, and it's made right here in the USA.

Frequently Asked Questions
What press does the RCBS Matchmaster seating die fit?
The 24040 has a standard 7/8"-14 thread, so it's compatible with any RCBS reloading press and most other presses that accept dies with this universal thread size. Check your press manual if you're unsure.
Does this seating die come with sizing dies or other components?
No—this is the seating die only. You'll need to pair it with a sizing die, primer feeder, powder measure, and other components appropriate for your cartridge and reloading setup.
How does the bullet retention system work?
The loading window features an internal sleeve that catches and holds the bullet in alignment with the case as you lower the press ram. The free-floating, self-centering seating stem then guides the bullet straight onto the case mouth, eliminating the need to balance or hand-position the bullet and reducing the risk of misalignment or injury.
Can I adjust the seating depth while reloading?
Yes. The large micrometer knob allows you to dial in adjustments in one-thousandth-inch increments. The oversized markings and letters make it easy to read and turn precisely, so you can tweak seating depth as needed between batches.
