This Ultimate Trimmer Micrometer Attachment replaces the standard L.E. Wilson adjustment screw. The Starrett one inch travel micrometer head allows quick, accurate setting of the trimmer in increments of .001".

• The micrometer has a one-inch travel, so lengths of the longest and shortest cases you plan to trim must be within 1" of each other.
• Recording the settings enables you to dial back a setting when changing from one cartridge case to another.

You will need to order the Micrometer Conversion Kit which includes a Special Nut and Tip, in order to use this with your trimmer.
