If he likes Tikka, then I doubt anything will be better enough at lesser price to bother too much pondering.
Savage is great as well, i have one, but I like the looks of Tikka better...accuracy very good n both.

Not out of the box compared to a Tikka or Savage. If you have a smith then a remington action may be the most universal platform, but not the most accurate out of the box.
I've had a few Remington 700's .270's that would shoot 1/2" or better right out of the box. A friend of mine had one that would hover around 1/4". This wasn't recently so I don't know what they are putting out now but I've seen quite a few shoot really well.
The T3 will do him fine. It wouldn't be my choice but it will definitely get the job done at 300 + yards.
I dislike the shortcuts that Tikka/Sako took with the T3 but understand that it's all about staying at a certain price point. Personally I would not go with a .27 cal since higher BC bullet selection is limited.
