I shot a 6.5WSM for more than a few years, and had several built around the Winchester single shot action.
The velocities the PRC generates are comparable that Old badger and I were getting with our 6.5WSM's using 140 grain match Kings, Lapua Scenars and 140 Barnes bullets.
being a 6.5 bullet , the accuracy will be exceptional and flat as long as the barrel is a good one.
I killed several deer with my rifle that had the 28" barrel on it, some at distances beyond "normal"
if I were looking for a hunting 6.5 I would be really tempted to get one as I cannot find a downside to a cartridge where factory brass is available, especially a 6.5
