I have both in AR builds and have decided to see if there is any kind of advantage one might have over the other. Both cartridges are necked down from grendel brass--but because the PRC shoulder is knocked back a bit I'm using nickle-plated brass for the predator (so I can tell them apart). Both are using 108 eldm's seated to 2.29 and 8028 XBR for powder. Because the ARC has slightly less H2O capacity I tried to match the loads with a bit less propellant in the ARC. Soon as it stops down-pouring outside I'll try to give them a go.
