Roll crimp seating dies are the most common type of crimping dies you will find. Roll crimping creates a reliable, firm crimp on cannelured bullets, and ensures that bullets will not dislodge themselves under recoil or chambering. To seat bullets with no cannelure, simply unscrew the die to disengage the roll crimping mechanism.
Dies are the heart of the reloading process, and RCBS is the industry leader for quality dies. Engineered to the highest standards and manufactured to the tightest tolerances, theyre constructed from case-hardened steel, precision-drilled, reamed, polished and hand-inspected twice before leaving the factory. No other manufacturer holds their product to such a high standard.
