The Universal Bullet Seating Die works with .224 to .338 caliber bullets. Featuring a cutout window die body, the Universal Bullet Seating Die holds the bullet in place while seating. The built-in micrometer allows for precise .001 micro-adjustments to the seating depth of the bullet. Includes 9 bullet alignment sleeves, 3 VLD bullet seating stems and a molded storage case. (Note: one alignment sleeve and one VLD bullet seating stem are pre-assembled inside the die.)
