Lee Precisiom
The Lee Precision 338 Arc Rifle Precision Micrometer Bullet Seating Die brings repeatable, dead-length seating control to your reloading bench without the premium price tag. Built for handloaders who demand tight bullet-to-case concentricity and consistent seating depth across every round, this die combines precision engineering with intuitive adjustability. Whether you're assembling match ammo for long-range hunting or building loads for the range, the micrometer adjustment system lets you dial in your exact seating depth and return to it reliably, shot after shot.
The laser-engraved micrometer thimble reads in thousandths of an inch—just like a precision depth gauge—so you're never guessing at your settings. The floating bullet guide is the real workhorse here: it holds the case and bullet in perfect alignment while allowing radial clearance so they can center themselves naturally. This design minimizes bullet runout and prevents the marking or deformation that can happen with rigid seating stems. The stem itself is machined and burnished smooth, so it handles soft-point, hollow-point, and other bullet profiles without damage.
One of Lee's signature moves with this die is the reversible floating guide. Unthread it and flip it back in, and you can seat and crimp in a single stroke—a convenience feature you won't find everywhere. For reloaders chasing accuracy on a real-world budget, this is a genuinely capable tool that doesn't ask you to compromise on functionality or consistency.
| Brand | Lee Precision |
| Product Type | Rifle Precision Micrometer Bullet Seating Die |
| Caliber | 338 Arc |
| Adjustment Resolution | .001" (one thousandth of an inch) |
| Seating Method | Dead length |
| Floating Guide | Reversible; allows simultaneous seating and crimping |
Yes. The floating bullet guide is reversible—unthread it and reinstall it upside down to enable simultaneous seating and crimping in one press stroke. This is an exclusive Lee feature on this die.
No. The bullet seating stem is machined and burnished smooth to handle soft-point, hollow-point, and other bullet profiles without marking or deformation.
Dead-length seating means the die body contacts the shell holder, ensuring precise and uniform seating depth every time you use the die. This consistency is what allows the micrometer adjustment to give you repeatable results across all your rounds.
The micrometer thimble is laser-engraved with divisions representing one thousandth of an inch. It reads exactly like a precision depth micrometer, so you can dial your seating depth in thousandths and log it for future reloads of the same cartridge.
