6.5 PRC is kind of like the big brother of the 6.5 Creedmoor and much like the Creedmoor it has very good factory support.
The 6.5 PRC is nearly a ballistic twin to the 6.5-284 except the PRC requires a mag bolt face and works better in a short action where as the 6.5-284 has its best performance, especially with the 140 and up bullet weights in a long action.
I had some Cabela's points burning a hole in my pocket and bought a CA Ridgeline in 6.5 PRC awhile back. When I first got it I didn't have any dies for it yet and I was able to snatch up a few boxes of the Hornady 147 ELD-M ammo. I was pleasantly surprised when it shot that factory ammo in the .3's.
Is the 6.5 PRC the end all be all of the 6.5 world, no, but they generally shoot well, even with factory ammo, and they make for a nice setup in a short action.
