RCBS Competition Dies are meant for reloading bottleneck cartridges for competitive marksmen who measure success in fractions of a millimeter. The Seater Die doesn't crimp; it features a micrometer for super accurate bullet seating depth in increments of 0.001 inch, as well as a bullet loading window and a seating guide that ensures correct bullet alignment before and after seating.
