The Lee Precision 350 Legend Rifle Precision Micrometer Bullet Seating Die brings repeatable, hands-on control to your reloading bench. Built for handloaders who demand consistency shot after shot, this seating die combines straightforward mechanical precision with the kind of adjustability that lets you dial in exactly the seating depth your ammunition needs. Whether you're preparing match rounds or hunting loads, the micrometer-based system eliminates guesswork and makes it easy to document and replicate your settings.
At its core, this die uses dead-length seating—the body contacts your shell holder, ensuring the same seating depth every single time. The floating bullet guide does the heavy lifting here, keeping the case and bullet in perfect alignment while you seat. That floating design is reversible too; flip it around and you can seat and crimp in one stroke, a feature Lee built in so you can streamline your process without swapping dies. The guide provides radial clearance, so it adapts to slight variations in case dimensions without binding or forcing misalignment.
The micrometer thimble is laser-engraved with easy-to-read divisions in thousandths of an inch, working just like a precision depth micrometer you might use in a machine shop. That means infinite adjustment—no detent clicks, no preset stops, just your judgment and the dial. The seating stem itself is machined and burnished to handle nearly any bullet point style without marking or deforming the projectile, a detail that matters when you're trying to maintain bullet integrity and consistency.
For 350 Legend reloaders who want to take command of their ammunition without spending a fortune, this die proves that precision and affordability aren't mutually exclusive. It's the kind of tool that rewards attention to detail and makes your reloading sessions more efficient and reproducible.

Yes. The floating bullet guide is reversible—simply unthread it and reinstall it facing the opposite direction. This allows you to seat and crimp simultaneously, eliminating the need to swap dies between those two operations.
The micrometer thimble reads in thousandths of an inch, just like a precision depth gauge. You can measure your target seating depth with calipers or a comparator, dial the micrometer to that setting, and then repeat it consistently. The die body's contact with the shell holder ensures that same depth is replicated every time you lower the ram.
The seating stem is machined and burnished specifically to seat nearly any bullet point style without marking or deforming the projectile, so you can maintain bullet integrity and consistency throughout your load.
This die is sized and designed for 350 Legend. For other calibers, you'll need the appropriate caliber-specific die.
