Lee Precision 277 Sig Fury Rifle Precision Micrometer Bullet Seating Die
The Lee Precision 277 Sig Fury Rifle Precision Micrometer Bullet Seating Die gives handloaders the control they need for repeatable, uniform round assembly without the premium price tag. Built for reloaders working with 277 Sig Fury ammunition, this die combines a micrometer-adjustable seating stem with a floating bullet guide design that keeps cases and bullets in perfect alignment throughout the seating process. Whether you're fine-tuning loads for a bolt-action hunting rifle or dialing in precision ammunition at the range, the micrometer adjustment lets you lock in consistent seating depth to the thousandth of an inch.
The laser-engraved micrometer thimble reads intuitively—just like a precision depth micrometer—so you can dial your exact seating depth and replicate it with confidence across your entire batch. The machined and burnished seating stem seats bullets cleanly without marking or deformation, and the floating bullet guide's radial clearance ensures the bullet and case mouth stay centered with the seating screw, minimizing runout. When used as a dead length die, the die body contacts the shell holder directly, giving you the precise reference point needed for uniform seating depth shot after shot.
A distinctive feature for reloaders seeking efficiency: the reversible floating bullet guide can be unthreaded and reinstalled to allow simultaneous seating and crimping in a single stroke—an option unique to Lee's design. This die proves that achieving accuracy in handloading doesn't demand deep pockets, just smart engineering.
