The "Competition Pro Series" three(3) die set is designed for use in progressive reloading machines by reloaders seeking the most advanced bullet alignment available. This deluxe version of our Pro Series die set also contains our Titanium Carbide sizing die and Profile Crimp Die. (Taper crimp dies for cartridges that headspace on the case mouth.) No expander die is included, as the most popular progressive machines expand the case mouth at the powder metering station. The Competition Seating Die and crimping die have a special large radius at the mouth for easy case entry.
