The L.E. Wilson 243 Ackley Improved Micrometer Top Bullet Seater Die (part no. S24-ACK) is a precision bullet seating die with a micrometer-adjustable top, letting 243 Ackley Improved handloaders dial in and repeat an exact seating depth load after load. Made by L.E. Wilson, it uses the Wilson case-length gauge and arbor-press system, giving competition and precision shooters the fine control a standard seater doesn’t offer. The micrometer top reads in thousandths of an inch, so once a load is dialed in, a handloader can return to it session after session without re-measuring from scratch.
