L.E. Wilson 338 Edge Bullet Seating Die

The L.E. Wilson 338 Edge bullet seating die brings benchrest-level precision to your reloading bench. Unlike conventional seating dies, this chamber-type seater uses a capture design that controls both bullet and cartridge case alignment before seating, resulting in dramatically lower runout and more consistent loads. If you're chasing tight groups at distance or demand the most accurate ammunition for your 338 Edge, this die is built to deliver.

What sets Wilson's chamber-type design apart is how it works: your case and bullet are fully captured and aligned by the die before the close-fitting seating stem pushes the bullet straight into the case mouth. That positive control eliminates the wiggle and misalignment that plague standard 7/8"-14 TPI seaters, which is why serious benchrest shooters have relied on Wilson seaters for decades. The result is ammunition with runout so low that you'll see the difference on target.

Every die is machined from stainless steel for durability through hundreds of reloading cycles. Depth adjustment is handled via a cap screw (3/8"-24 TPI), giving you fine control over seating depth. The die ships with a seater base, allen wrench, and instructions—everything you need to integrate it into your reloading setup right away.

Frequently Asked Questions

How does a chamber-type seater differ from a standard 7/8"-14 seating die?

A chamber-type seater captures both the case and bullet before seating begins, aligning them precisely and then pushing the bullet straight into the case mouth with a close-fitting stem. Standard 7/8"-14 dies don't offer this capture control, so you get more alignment variation and higher runout. That's why Wilson's design is favored by benchrest shooters who need every round to be identical.

Will this die fit my reloading press?

This is a Wilson chamber-type seating die for the .338 Edge. Confirm your press accepts standard reloading dies; the die itself is compatible with most single-stage and progressive presses that use universal die threads. If you're unsure about your specific press, contact us before ordering.

What comes in the box?

You'll receive the seater die, seater base, an allen wrench for adjustments, and printed instructions. Everything needed to get started; you supply the press and reloading components.

Is this die suitable for hunting loads, or just match/benchrest ammunition?

While this die was developed and proven by benchrest shooters, the precision it delivers—controlled runout, consistent seating depth—benefits any reloader who wants accurate, reliable ammunition. Whether you're loading for hunting, range work, or competition, lower runout means better performance on target.
