Rio hulls feature easy-loading straight-wall extruded tubes and deep plastic disk basewads for versatile load designs.
Like Fiocchi, Rio's proprietary primer is made in Europe to a metric specification. The result is that the primer measures approximately 0.001" larger than standard U.S. primers. Therefore, plan on reloading them with Fiocchi or Rio primers - otherwise a U.S. primer will be loose in the primer pocket. Of course, primer pockets can always be repaired with a Primer Pocket Conditioner tool.
