The “Competition Pro Series” three (3) die set are designed for use in progressive reloading machines by reloaders seeking the most advanced bullet alignment available. All progressive die sets are supplied with the profile crimp die (or taper crimp die if the cartridge headspaces on the case mouth) because the best possible crimp is attained after the bullet is seated with the included Competition Bullet Seating Die. An expander die is not included in these sets as the most popular progressive machines expand the case mouth at the powder drop station. All Pro Series Die Sets are designed with a special large radius as the mouth of the seating and crimping dies for easy case entry.
