I think the Tikka will fit the bill just fine. My sons 270 wsm in a tikka has been the easiest gun I have ever worked up a load for, it likes em' all.
Although savage or a marlin xl7 are good but Tikka's just shoot real well..
I have got several savages that extremely accurate. Most all will shoot sub moa and if i do my part 1/2 moa. My wife on the other hand has a tikka that will shoot just as good as my savages. The tikka did take a little more ammo to work the load that i wanted but is still a shooter.
I bought the Tikka T3 Hunter .270 this season, and I really like it. It seems like the best value out there in terms of what you get for your money. I don't think you'll go wrong picking that gun. No additional work from a gunsmith. Really a great gun.
