Built to slightly different dimensions than the regular RCBS dies to allow optimum seating and crimping needed to load great lead bullet ammo. Heat treated for a more authentic appearance. Handsome brass lock rings and period style packaging complement these premium dies. Shellholder sold separately.
- For use in CAST BULLETS ONLY.
- The roll crimp rolls the case out onto the side of the bullet.
- As the seater pushes the bullet into the case, the shoulder of the die crimps the case against the bullet.
