RCBS 3-Die Set 45-120-3 1/4

The 3-Die Roll Crimp Set is designed specifically for reloading straight-wall cartridges. The steel Sizer Die sizes the case and de-primes it, ensuring it's ready for reloading. It's essential to lubricate the cases to prevent sticking. The Expander Die expands the case to the proper diameter to properly fit the bullet and it creates a flare or bell at the case mouth, aiding in smooth bullet feeding. Finally, the Seater Die seats the bullet in place and applies a roll crimp to secure it, ensuring reliable and consistent performance in your reloads.
