Precision Bullet Seating Made Simple

The Lee Micrometer Precision Bullet Seater represents a straightforward approach to one of reloading's most critical operations: consistent bullet seating depth. This die delivers the accuracy serious handloaders demand without unnecessary complexity or expense.

Key Features

• Micrometer-Controlled Depth: Laser-engraved thimble with divisions representing one-thousandth of an inch—readable like a precision depth micrometer
• Floating Bullet Guide: Radial clearance allows perfect alignment between case, bullet, and seating stem, minimizing bullet runout
• Reversible Design: Unthread and reinstall the guide to enable simultaneous seating and crimping in a single stroke
• Precision Machining: Burnished seating stem accommodates nearly any bullet point style without marking or damage
• Dead Length Seating: Body contacts shell holder for uniform, repeatable seating depth across all cartridges

Why This Matters

Bullet runout—the wobble of a seated bullet—directly affects accuracy. Lee's sliding bullet guides have been tested to produce cartridges with minimal runout. The floating guide design ensures your case and bullet remain in perfect alignment throughout the seating process.

The micrometer adjustment provides infinite precision, allowing you to dial in exact seating depth and return to that setting shot after shot. This consistency translates directly to tighter groups downrange.

Built for Reloaders

Whether you're loading match ammunition or hunting rounds, this die proves that precision doesn't require premium pricing. The reversible guide adds versatility, and the straightforward design means less time troubleshooting and more time at the range.
