I had a 6.5x55 Ackley built on a barnard S action and I am very happy with it. It was built by Tony Halberg and John Hastie, these guys are very good smiths. this rifle consistently shoots around the .300'' mark at 100 yards.
The Barnard S action with the magazine would be a good choice with a mcmillan edge stock or similar, and with a good barrel would get you well past 600 yards!
I would also stick with the 7mm-08 cartridge in a 24'' spout, it will still easily kill at that range. Stepping up to say a 280 Rem in that barrel length will just make more muzzle blast and noise without a huge increase in performance.
