Neck Sizer Dies by RCBS specifically size only the case neck of a 300 Winchester Magnum cartridge, preserving the case body and shoulder dimensions.
The die decaps spent primers and sizes the neck for proper bullet tension using an expander ball, ensuring a precise fit when cases are re-fired in the same rifle.
These dies are compatible with all 7/8 to 14 reloading presses and come in a protective RCBS plastic die box.
