RCBS Full Length Die Set .223 WSSM - 10501

This two-die set is designed for reloading .223 WSSM bottleneck rifle cases and includes a Full-Length Sizer Die with Expander-Decapping Unit and a Seater Die with Bullet Seater Plug. The sizer die brings cases to SAAMI minimum dimensions, sizes the case exterior, decaps, and expands the neck, while vents prevent case damage from trapped air and excess lubricant.
