Lee Precision 30-40 Krag Rifle Precision Micrometer Bullet Seating Die

The Lee Precision 30-40 Krag Rifle Precision Micrometer Bullet Seating Die brings consistency and control to your handloading bench. Whether you're working up loads for a classic Krag or fine-tuning ammunition for precision rifle work, this die gives you the repeatability that matters when every round counts. The micrometer-adjusted seating stem lets you dial in your exact seating depth with confidence, eliminating the guesswork that plagues standard dies.

What sets this die apart is the engineering underneath. A floating bullet guide keeps your case and bullet in perfect alignment as they meet the seating stem, which means minimal runout and consistent seating from round to round. The guide itself is reversible—flip it around and you can seat and crimp in the same stroke, a feature exclusive to Lee that saves you a die station and keeps your setup simple. The micrometer thimble is laser-engraved with clear graduations in thousandths of an inch, reading just like a precision depth gauge, so you know exactly where you are every time you adjust.

The seating stem is machined and burnished smooth, so it seats bullets cleanly without marking or deforming them, whether you're running soft tips, boat-tails, or match-grade rounds. As a dead-length die, the body contacts your shell holder to lock in seating depth, eliminating variables and delivering the precision you expect from a micrometer system without the premium price tag.

Frequently Asked Questions

Will this die work for both seating and crimping?

Yes. The reversible floating bullet guide allows you to combine seating and crimping in one stroke by simply unthreading the guide and reinstalling it in the opposite orientation. This is an exclusive feature to Lee's micrometer dies.

How precise is the micrometer adjustment?

The micrometer thimble is graduated in thousandths of an inch (0.001 inch), and the markings are laser-engraved for easy reading. This level of adjustment gives you the precision needed for consistent, repeatable seating depth.

Will this die damage my bullets?

No. The seating stem is machined and burnished smooth specifically to seat bullets cleanly without marking or deforming them, regardless of point style or construction.

Is this a dead-length seating die?

Yes. The die body contacts the shell holder to establish seating depth, which is the dead-length principle. This eliminates variables and ensures uniform seating across your rounds.
