RCBS 360 Buckhammer Roll Crimp 3-Die Set

The 3-Die Roll Crimp Set is specifically designed for loading straight wall cartridges, providing all the necessary components for a precise and efficient reloading process. The steel Sizer Die sizes the case and de-primes, ensuring uniformity and readiness for the next steps (note: cases must be lubricated). The Expander Die expands the case to the correct diameter for bullet seating and imparts a flare or bell at the case mouth for smooth bullet feeding. Finally, the Seater Die seats the bullet and applies a roll crimp, securing the bullet in place for a reliable and consistent round. This die set is an excellent choice for reloaders seeking optimal performance with straight wall cartridges.
