The Redding Bullet Seating Micrometer STD #18 Seat Plug is a precision replacement component for handloaders who demand consistency and repeatability in their ammunition assembly. This micrometer-equipped seat plug works with most standard Redding seating dies, letting you swap it between dies without fuss and dial in exact seating depth with confidence. If you're loading traditional bullet shapes—round-nose, spire-point, flat-base—this standard (STD) version is built for you.
Precision handloading lives or dies on small details. A worn or damaged seat plug degrades the consistency of your seating depth, which ripples through velocity, accuracy, and pressure. This direct replacement lets you restore your die to original specifications without replacing the whole assembly. The micrometer interface gives you the fine control that match-grade and competition handloaders expect.
The #18 designation indicates this plug is sized for the corresponding Redding die cavity. Installation is straightforward—no special tools needed—and you can move it from one compatible die to another as your loading needs shift. Keep one on the bench as a spare, or maintain a dedicated micrometer plug for each of your most-used calibers to lock in your preferred seating depths and eliminate setup time.
Not compatible with Redding Competition Seating Dies, so verify your die model before ordering. For VLD (very low-drag) bullet designs or flat-nose handgun bullets, Redding offers matching micrometer variants.
