I bought a die i dont know if it is the right one i needed. I bought a RCBS 223 X-sizer die. Is this the right die. I read with this die you dont have to trim your brass . I still have to but a bullet seating bullet. And thought about buying a used RCBS small base die and a bullet seating die to go with my X - SIZER die. Or do i need a small base die. VM :roll:
