Rcbs NECK EXPANDER PLUG 0.416'' 39883

To eliminate deforming the base and shaving lead off the sides of your lead rifle bullets during seating. RCBS strongly recommends using their Neck Expander Die. In one step, the neck expander die expands the neck and slightly flares the case mouth of your bottle neck cases. This is the expander plug only, to be used with the body die.
