I got a Ruger American Predator in 6.5 CM and it is accurate! You can also get it in the standard American form with the lighter barrel.
Recently I added a Boyd's Classic laminated stock (1 lb. heavier) and a Timney trigger to my RAP. This week I'll be going out to re-sight it and I think it will shoot better, say 1/2 MOA where before it was doing 3/4 MOA with Hornady 143 gr. ELD-X ammo.
I'll put the lighter factory plastic stock back on when I hunt at high altitude (above 8,000 ft.) I kinda thing the POI don't change too much but it's always best to check zero before hunting. That Boyd's stock is just beautiful and precisely made.
Soon I'll start reloading for it and its "big brother", my Ruger Precision Rifle, also in 6.5 CM.
If I wanted to spend more money I would have bought the Tikka in 6.5 CM. But I can't see how it would be any more accurate than my RAP.
BTW, check out the "6.5 Creedmoor Forum". Lots of good info there.
