Lee Precision 360 Buckhammer Rifle Precision Micrometer Bullet Seat Die

The Lee Precision 360 Buckhammer rifle precision micrometer bullet seat die brings repeatable, dead-length seating to your reloading bench without the premium price tag. Built for handloaders who demand tight runout and consistent case-to-bullet concentricity, this die uses a floating bullet guide and micrometer adjustment system to achieve the kind of accuracy traditionally reserved for high-end setups. If you're loading precision ammunition for hunting, competition, or long-range shooting, a micrometer seating die transforms your ability to dial in exact seating depth and dial-to-dial consistency.

The standout feature here is the laser-engraved micrometer thimble and body, graduated in one-thousandth-inch increments—reading just like a precision depth micrometer. That makes adjustment intuitive and repeatable; you can dial in a seating depth, write it down, and hit that same mark every time you load a batch. The machined and burnished seating stem seats bullet points cleanly without marking, and the floating bullet guide keeps the case and bullet perfectly aligned through the stroke, which is where your runout control comes from.

Lee's reversible floating bullet guide is a practical touch: unthread it and flip it back in to enable simultaneous seating and crimping if your workflow calls for it. The die's body contacts the shell holder under the floating guide principle, guaranteeing that seating depth is set off dead length rather than case length variables. This approach minimizes shot-to-shot variation in seating depth and is the core reason why precision shooters and careful handloaders rely on micrometer seating dies. Whether you're running a progressive press or a single-stage, this 360 Buckhammer die fits standard Lee press threads and plays well with the rest of your equipment.
