Lee Precision 220 Swift Rifle Precision Micrometer Bullet Seating Die

The Lee Precision 220 Swift Rifle Precision Micrometer Bullet Seating Die brings repeatable, precise seating depth to your handload bench without the premium price tag of boutique reloading equipment. Built for 220 Swift cartridges, this die features a micrometer-adjusted seating stem that lets you dial in bullet depth with confidence—dead-length seating keeps every round consistent, shot to shot. Whether you're a precision rifle shooter fine-tuning loads for accuracy or a volume reloader who needs reliable results, this die delivers the control serious handloaders expect.

The floating bullet guide is the standout innovation here. It holds your case and bullet in perfect alignment during seating, then reverses to allow simultaneous seating and crimping—a feature unique to Lee that saves a die station on your press. The micrometer thimble is laser-engraved in thousandths-of-an-inch increments, reading just like a precision depth gauge so you can dial your exact seating depth and return to it run after run. The seating stem is machined and burnished to handle nearly any bullet point style without marking or deforming the projectile.

Tests confirm that the radial-clearance floating guide design produces cartridges with the lowest bullet runout of any comparable die—critical for long-range accuracy and consistent ballistics. When used as a dead-length seater, the die body contacts the shell holder, ensuring uniform seating depth that translates to shot-to-shot velocity and impact uniformity. If you're serious about reloading precision ammunition for your 220 Swift, this die gives you the adjustability and repeatability you need at a fair price.

Frequently Asked Questions

Can I use this die to seat and crimp in one step?

Yes. The floating bullet guide is reversible—simply unthread and reinstall it to switch between seating-only and simultaneous seating-and-crimping modes. This exclusive Lee feature lets you combine operations and save a die station on your press.

What's the advantage of the floating bullet guide?

The floating guide holds your case and bullet in perfect alignment during seating while allowing radial clearance so they self-center. Tests show this design produces cartridges with the least bullet runout, which improves accuracy and consistency downrange.

Will this die mark or damage my bullets?

The seating stem is machined and burnished to handle nearly any bullet point style without marking or deformation, protecting your projectiles during the seating process.

How do I know how deep I've seated the bullet?

The micrometer thimble is laser-engraved with divisions representing one thousandth of an inch, so you read it just like a precision depth micrometer. Once you dial in your seating depth, you can return to it precisely every time.
