I'd lean towards a 6 arc in chambering, right up to where tikka & weatherby don't do it... lol
At least currently the 243 smokes the 6cm on ammo availability, and tikka spins them 1:8 to allow you to shoot heavies. To me the 6cm is a new wrapper over the tried and true 243.
On second thought, with the 6arc, your factory ammo will be ar15 friendly stuff and 250 fps slower than a bolt gun should sling them. Id do 243
