The PRC is roughly 200-300 fps faster than a Creedmoor, with the same bullets at the same pressures. The 6.5×284 is nearly the same case capacity, and set up correctly will do everything the PRC will do. There are two main issues with the 6.5×284. The first is the non-standardized chamberings. The second is the COAL.
