Wilson Stainless Steel Micro-Adjustable Bullet Seater Cap for Standard Inline Seater Die
$52.80
If you're serious about handload precision, the L.E. Wilson Stainless Steel Micro-Adjustable Bullet Seater Cap transforms your standard inline seater die into a micrometer-grade seating tool. This is the upgrade path for reloaders who've hit the limits of fixed-depth caps and want to dial in bullet seating depth to the thousandth of an inch without swapping dies or wrestling with trial-and-error adjustments.
The cap threads onto any standard L.E. Wilson seater die and lets you fine-tune seating depth in .001" increments, with a full rotation moving the bullet .025" deeper or shallower. Those precision-cut 40 tpi threads feel smooth under your fingers and hold their settings reliably, shot after shot—critical when you're chasing sub-MOA loads or sorting ammunition for benchrest. Because it's machined from 303/316 stainless steel and maintains the same compact profile as a standard Wilson cap, it bolts into your existing setup without adding bulk or complexity.
The micro-adjustable cap accepts Wilson seating stems for .17 to .35 caliber bullets, so whether you're loading .223, .308, or anything in between, you've got the range covered. Laser-etched depth markings stay crisp and legible through years of use—no fading like hand-stamped indicators. And because Wilson caps are engineered to hold bullet and case in perfect alignment during the seating stroke, you're getting concentricity and runout control built into the design, not fighting it.
If you already own L.E. Wilson dies, this cap is a straightforward path to repeatable, documented seating depths on every round. Swap it in, lock it down, and you're dialing precision into the most critical step of the handloading process.

Frequently Asked Questions
What L.E. Wilson seater dies does this cap fit?
The micro-adjustable cap is designed to replace the standard cap on L.E. Wilson inline seater dies. It threads onto the standard seater die body without requiring any die modifications.
What calibers can I load with this cap?
This cap accepts L.E. Wilson seating stems (drifts) for .17 to .35 caliber bullets, covering most rifle and pistol cartridges in that range. You'll need the appropriate seating stem for your specific caliber.
How much finer is the adjustment compared to a standard seater cap?
The micro-adjustable cap allows you to dial seating depth in .001" increments via the micrometer threads. A full rotation changes seating depth by .025", giving you precise control for load development and consistency that fixed caps cannot match.
Is this cap easy to install on my existing die?
Yes—simply unscrew the standard cap from your L.E. Wilson seater die and thread the micro-adjustable cap in its place. Tighten the setscrew and you're ready to adjust and dial in your seating depth.
