The micrometer adjust screw by Lee Precision replaces the original adjusting screw on any Lee bullet seating die.

Infinitely adjustable, allows precision bullet seating depth.

Easy to read laser engraved divisions represent .001" one thousandth of an inch.

The integrated friction ring eliminates annoying clicks that prevent splitting thousandths. No clicks, just smooth adjustment.

Reads just like a precision depth micrometer, record your setting and easily return to them for future use.
