Large Caliber Rifle Micrometer adjusting screw with red 4 die storage case. Allows you to keep your micrometer installed on your Lee bullet seating die inside of the case.

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. The micrometer adjuster can be easily transferred to other Lee Bullet Seating Dies but it is so economically priced you will want one for every die.
