LEE 92221 .308 Winchester Micrometer Precision Bullet Seater Die

The LEE 92221 .308 Winchester Micrometer Precision Bullet Seater Die delivers consistent bullet seating depth with micrometer-adjustable precision for match-grade ammunition. This advanced seating die eliminates guesswork by providing exact, repeatable bullet depth control measured in thousandths of an inch.

What Makes This Different

Unlike standard bullet seating dies that rely on trial-and-error adjustments, this micrometer-equipped die features graduated markings for precise depth control. The built-in micrometer head allows adjustments in 0.001-inch increments, ensuring consistent cartridge overall length (COL) across entire loading sessions. Standard dies require multiple test rounds to achieve desired seating depth, while this system delivers accuracy on the first attempt.

Key Features

• Micrometer adjustment head with 0.001-inch precision increments
• Hardened steel construction with machined threads for durability
• Compatible with all standard 7/8-14 TPI reloading presses
• Floating bullet guide prevents bullet deformation during seating
• Graduated scale markings for consistent depth reference
• Includes bullet seating stem for .308 Winchester projectiles
• Lock ring secures die position in press turret

This precision seating die maintains consistent bullet jump measurements critical for accuracy in bolt-action rifles and precision AR-10 platforms. Competition shooters benefit from the repeatable seating depths that eliminate flyers caused by inconsistent cartridge dimensions. The micrometer adjustment allows fine-tuning of bullet seating for different powder charges or bullet weights without removing the die from the press.
