Hmmm. For hunting, it will surely kill, but.... It was conceived as a long-range target cartridge that pushes high-BC bullets at near-extreme velocities. The thinking was "if 6.5 CM is good, 6.5 PRC is better," with "better" meaning "faster"--in this case, by about 200 fps It's not known for providing long barrel life--with some saying that 900 shots are where your accuracy starts declining.
I wouldn't be surprised if ammo manufacturers will continue riding this 6.5 craze to the next level--perhaps by ultimately necking down a 40mm Bofors shell and trimming it to fit a .308 Win size action.
Thing is, there's a "wall" beyond which rifle round velocities can't be pushed, and these new long-BC screamers are not far from it. If velocity and long distances are your cup of tea, go for it. For some reason, I've never developed an interest in velocity and long-distance hunting--perhaps it's my old age.
