Lee Micrometer Precision Bullet Seater Die - 357 Magnum, 38

The Lee Micrometer Precision Bullet Seater is a single seating die for reloaders loading 38 Special and 357 Magnum who want repeatable seating depth and straighter ammunition. A floating bullet guide keeps the case mouth, bullet and seater screw in line to cut bullet runout.

Depth is set on a laser-engraved micrometer body with smooth, click-free adjustment. Dead-length seating with the die body on the shell holder keeps depth consistent from round to round.

Key Features

• Less runout – the floating bullet guide holds case mouth, bullet and seater screw in alignment, and Lee reports its sliding guide gave the lowest runout in testing.
• Repeatable depth – dead-length seating with the body contacting the shell holder gives uniform seating depth.
• Easy to read and set – the machined, burnished one-piece body is laser engraved and adjusts smoothly with no clicks.
• No marks on bullets – the precision-threaded seating stem suits most bullet nose shapes without marking them.
• Seat and crimp option – the bullet guide can be converted to seat and crimp in a single operation.
• Wadcutter ready – Lee offers a separate flat-nose seating screw for wadcutter and semi-wadcutter bullets.
