L.E. Wilson has been making precision reloading tools for over 80 years. This Stainless Steel micrometer seater allows reloaders to easily dial how deep they want to seat a bullet. Turn any L.E. Wilson precision Chamber Type Seaters into a micrometer adjustable die. Just remove the standard Bullet Seater cap and thread the Micrometer cap on, adjust set screw and that's it. The compact design is about the same as the standard cap that is supplied with the die. The precision adjustment is measured in .001" increments of seating depth. Both bullet and case are firmly held in perfect alignment as the bullet is seated in the case to help increase concentricity and minimize bullet runout. Hand-die design for use with a mallet or an arbor press. Not for use on a conventional press.FeaturesAccepts all calibers of Seating stems (Drifts) 17 to 35 caliberAdjust in .001 increments with .025 per full rotation - easier to dial in seating depthLaser etched lettering and scale
