This is a 65mm case, long action the 6.5 PRC is, ostensibly, a short action cartridge.
This is basically the 7LRM, but in .30 cal. This is what the new sniper rifles SHOULD have been chambered in, instead of .300 WM (approx 5 grains more capacity in the same envelope).
More ass than the .300 WM, less than the ultra-mags and Nosler offerings. Same .532 boltface as standard magnums just no retarded belt.
