L.E. Wilson Stainless Steel Chamber Type Bullet Seater Die .338 Lapua
$79.20
The L.E. Wilson stainless steel chamber type bullet seater die for .338 Lapua is built for reloaders who demand precision and consistency shot after shot. Unlike conventional seating dies, this chamber-type design captures both the case and bullet before seating, ensuring perfect alignment every time. The result is concentricity and runout control that separates good ammunition from match-grade ammo—which is why benchrest and long-range shooters have trusted Wilson chamber-type seaters for decades.
What makes this seater different is the mechanics: your case and bullet are held in precise alignment by the die itself before the close-fitting seating stem pushes the bullet straight into the case mouth. This controlled, direct approach outperforms the conventional 7/8"-14 TPI seating dies you'll find in most reloading kits. Depth adjustment via cap screw (3/8"-24 TPI) gives you repeatable, fine-tuned control over seating depth, critical for consistent velocities and accuracy at distance.
Machined from stainless steel for durability and corrosion resistance, this die handles the demanding work of precision reloading year after year. It comes with the seater die, seater base, Allen wrench, and instructions—everything you need to integrate it into your .338 Lapua reloading setup. Made in the USA.

Frequently Asked Questions
How is a chamber-type seater different from a standard reloading seating die?
A chamber-type seater captures both the case and bullet inside the die before seating begins. This alignment happens before the seating stem makes contact, ensuring the bullet goes in perfectly straight. Standard 7/8"-14 TPI seaters don't offer this level of capture, which is why chamber-type designs produce lower runout and tighter concentricity—essential for precision shooting.
What comes in the box?
The die arrives with the seater die itself, a seater base, an Allen wrench for adjustment, and printed instructions—all packaged in a cardboard box.
What is the depth adjustment mechanism?
Seating depth is controlled via a 3/8"-24 TPI cap screw, allowing you to fine-tune exactly how deep the bullet seats into the case. This repeatability is crucial for consistent velocities and accuracy.
Is this die compatible with standard reloading presses?
This die is specifically designed for .338 Lapua reloading. Compatibility with your particular press setup depends on your equipment—consult your press manual or contact L.E. Wilson directly if you have questions about fit.
