Super precise - Forster Ultra Micrometer Seater Die

My Hornady match-grade would seat to an average of 2.1 1,000ths run-out this Forster seats better than half that, under a half 1,000th every time. Largely because the Forster holds the case all the way down to the base of the brass to assure the case is perfectly aligned with the projectile before pressing into the neck. This tightened up my sub-MOA's significantly.
