RCBS bullet seaters may also be purchased separately. Some reloaders like to have a separate seater die adjusted for each different bullet they shoot, or for different rifles of the same cartridge. RCBS seater dies have built-in taper or roll crimp ring appropriate for the cartridge. Seater dies are packed in an RCBS plastic die box and will fit any 7/8 to 14 reloading press.
