The Wilson Stainless Steel Chamber Type Bullet Seater with Micrometer Adjustment, is a favorite among bench rest shooters. The chamber type seater 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. Seating depth adjustments are made by turning the screw inside the cap and fine adjustments can be made with the built in micrometer. This along with the other bullet seaters Wilson makes are some of the most accurate bullet seaters ever made.
