I guess you're right that the 264 WM still has another 150fps over the PRC, which has about 200fps over the Creed. I thought I'd read that the PRC was roughly the same as 264 WM but not so. In working with my 264, I've noticed considerable differences in barrel heat depending on powders and of course charges. I migrate towards moderately slow powders rather than the super slow stuff and the barrel stays a LOT cooler. Admittedly, a 264 most of the time cannot benefit from its case capacity, but I've not seen evidence of erratic performance running charges of only 59gr.
I still find it funny how the 264 gets labeled as a barrel burner and no one talks of the 26 Nosler, 6.5-300 WM. Somehow these get a pass. The PRC is an interesting round and at some point I'll probably have one.
