Gtscotty, your posts remind me of the phrase "in theory there's no difference between theory and practice, but in practice there is". I said list SUITABLE 6.5 Creedmoor powders, not list every powder in a reloading manual capable of sending a piece of lead downrange. There are few ideal 6.5 Creedmoor powders ... just ask Hornady about that. Do you really want to burn up a 6.5 CM barrel with a load that shoots 3/4 moa or worse? There are numerous ideal .308 Win powders capable of producing 0.5 moa accuracy over a wide range of bullet weights. The same simply isn't true for the 6.5 Creedmoor. This won't be a deal breaker for some, but maybe for others it's worth considering and that's why I made the point.
As I said earlier, I have a number of .308 Win rifles and an AI with a 6.5 Creedmoor barrel, but unlike many here am not so enamored with the 6.5 CM. Inside of 500 yards I don't see the 6.5 CM offering any real advantage at all. Sure it's an accurate cartridge that is easy to load for with the right powder, but recoil is on par with the .308 Win, there aren't dedicated suppressors for 6.5 mm calibers (makes a difference re noise), and I consider a 140gr 6.5 CM bullet to be marginal for hunting anything but deer inside 300 yards in Montana. The .308 Win is an amazing all-around cartridge whereas the 6.5 CM is a purpose built paper puncher. That's my opinion and nothing more.
As for the PRS, if you have to strap large blocks of foam to your arms to help you shoot in awkward field positions then you are far more concerned with winning a game than developing your skills for practical shooting. To their credit, the PRS does have a Tactical class for .223 Rem and .308 Win, but I would find it more appealing if equipment was limited to "practical" equipment that you would want to carry in a pack while hunting or on a mission in the military. Again, just my opinion. For the record, I've signed up for the PRS Sniper's Hide Cup in June.
