Whoever wrote that article compared 24" test barrel factory ammo velocity with handloaded hotter Creedmoor rounds. For apples-to-apples, consider the factory 143 and 147gr Creedmoor loads (24" test barrel) of 2,700 and 2,695 fps respectively and compare them to the same 24" test barrel loads in the PRC that are 2,960 and 2,910 fps. That's a 215-260 fps velocity increase. The PRC case is considerably larger and loaded to a higher pressure than the Creedmoor, so yeah, hand loaders are already cranking them well over 3,000 fps.
The same article also states " If you need more speed than a 6.5 Creedmoor and want to stick with a .264-diameter bullet, then shoot a .260 Rem or 6.5-284 using a standard bolt." so, yeah, a 260? I'm not sure what the authors goal was here.
Perhaps the best explanation for this cartridge is to go to MidSouth or Midway etc and price 6.5x284 ammo (averages over $55/box), then look at the PRC ($35-37). While the 6.5x284 is fine for hand loaders, factory ammo is really expensive and not many companies want to load a really long, heavy bullet cause there's multiple chambering out there from years of hand loading before the Norma spec. The goal is to have affordable, factory ammo available (in addition to what hand loaders want) so that the average Joe can obtain and use high performance short-action 6.5 mag ammo and have a cartridge that fits and feeds in a wide variety of rifles.
