Micrometer Seating Dies

I also suggest that you buy and always use a loaded ammo (bullet) concentricity gauge.
Between that and a good set of well maintained dies (and press),I have never found the need for the micrometer type seater.
Knowing your bullets run out can sometimes solve alot of accuracy and pressure problems. --- SAWMAN
