I have seen little actual data for the .300 prc cartridge so far, but it seems very similar to the .30 Nosler. I think components for it will be more readily available than the Nosler cartiges have been though. Time will tell if it is going to be a winner or not.
The 6.5 prc seems to be producing some impressive data so far. A likely new favorite for barrel chambering.
I personally have serious thoughts of a model seven action paired with a 24" 6.5 prc barrel.
Anyone here have experience running one of these new calibers from Hornady at the range with some real would velocities, using hunting weght bullets?
