The L.E.Wilson Stainless Steel Micrometer Top Seater Dies positively controls both bullet and cartridge case alignment. The case and bullet are completely captured by the die prior to the bullet being pushed straight into the case by a close-fitting seating stem. This style of bullet seater works more accurately than a conventional (7/8"-14) bullet seating die. The stainless seaters have a built in micrometer seating depth adjustment feature with an easy to read scale in .001 graduations.
These die blanks allow the reloader to have a custom die made to their exact dimensions or for wildcat cartridges.
