3-DIE CARBIDE ROLL CRIMP SET - GROUP B - POPULAR REVOLVER CARTRIDGES

This 3-Die Set includes a Carbide Sizer Die, an Expander Die, and a Roll Crimp Seater Die.
The Carbide Sizer Die sizes the case and decaps the spent primer - The carbide sizer ring eliminates the need to lubricate. The Expander Die expands the case mouth to 'bell' or 'funnel' it so the bullet can be accepted into the case without shaving off lead. The Roll Crimp Seater Die seats the bullet and roll crimps the bullet in place to prevent it from pulling out during recoil to prevent cylinder jams.
