The shell plate and locator pins should be the same for the 6.5 PRC as they are for the 300 WSM. I use the 300 WSM conversion for my 7 SAUM. I haven't tried to use their powder funnel or any of that.
Shell plate, locator pins, dies and toolhead are all I use. Make sure you have the right primer tube and primer slide for the larger magnum primers.
