Overview
Built for handloaders working with straight-wall cartridges, this die set covers the core steps of case preparation, expansion, seating, and taper crimping in one setup. The steel sizer die sizes the case and de-primes it, while the expander die brings the case mouth to the proper diameter and adds the flare needed for bullet feeding. The seater die then seats the bullet and applies the taper crimp, making this a practical choice for organized loading bench work. Cases must be lubricated, and a shell holder is not included.
