Description
This is the L.E. Wilson chamber type bullet seating die for the 22 Hornet, the inline seater that a lot of precision handloaders consider the gold standard. Instead of threading into a traditional press, the case and bullet are completely captured inside a cavity that mimics your rifle's chamber. Once everything is lined up, a close-fitting stem pushes the bullet straight down into the case mouth. That tight fit between the stem and the die body is where the magic happens, and it's why these seaters have a reputation for producing exceptionally straight, concentric rounds.
Why the 22 Hornet Chamber Type Seater Works So Well
A conventional 7/8-14 threaded seating die relies on a sliding case and whatever tolerances come with it. The Wilson inline design takes the threads out of the equation entirely. The case face rests against the base and the bullet rides straight in, so there's very little room for runout to sneak in. With good case prep and consistent neck tension, this die rewards you with reliable, repeatable cartridge overall length round after round. It's machined from a solid bar of high-grade steel, hand reamed to the correct headspace, and built in the USA.
Running the Wilson 22 Hornet Seating Die
These dies are designed to be used with an arbor press, which gives you a great sense of feel as the bullet seats. You can actually read seating pressure and catch an inconsistent neck before it becomes a flier downrange. Seating depth on this standard model is adjusted by turning the seater stem, which you set by seating a dummy round, measuring, and fine tuning from there. Because the whole setup is so compact and simple, plenty of folks keep one in their range bag to tweak loads right at the bench.
It's been a favorite with benchrest competitors for decades, and over the years it's crossed over into F-Class, PRS, High Power, and just about any discipline where seating consistency matters. If you're loading the little Hornet for varmints or paper punching and you want to tighten up your groups, this is a smart upgrade.

Frequently Asked Questions
Do I need an arbor press to use the 22 Hornet seating die?
An arbor press is the way these dies are meant to be run, and it gives you excellent feel for seating pressure as the bullet goes in. You can get by with a soft-faced mallet or firm palm pressure in a pinch, but neither is as fast or consistent as a press. If you're serious about precision loads, pairing it with a quality arbor press is the right move.
Is this the micrometer-top version of the Wilson seater?
No, this is the standard chamber type model. Seating depth is adjusted by turning the seater stem rather than a micrometer dial. You set it by seating a dummy round, measuring your overall length, and fine tuning from there. It still delivers the same excellent concentricity the Wilson inline design is known for.
Does the Wilson 22 Hornet die require a shell holder?
No shell holder is needed. The case face simply sits against the base while the cartridge is fully captured inside the chamber-like cavity of the die. That's part of what keeps everything aligned and makes the loading rhythm so quick once you get going.
Will this seating die give me straighter rounds than my threaded dies?
That's exactly what the chamber type design is built for. By capturing the case and bullet in a cavity that mimics your rifle's chamber and pushing the bullet straight down, it removes the thread play that can introduce runout in conventional dies. With solid case prep and consistent neck tension, most loaders see noticeably more concentric ammo.
