I like 700's and have owned and used a boatload of them but the difference between the Tikka T3 and 700 is that the Tikka is ready to shoot well right out of the box. I have never owned or seen one that did not easily meet the guarantee of 3 shots under an inch. I bought my first T-3 about 20 years ago, I have bought some 700's since then but the 700's keep going down the road and the Tikkas stay.
If anyone ask me what rifle to purchase I unhesitatingly recommend Tikka. They are plug and play - requiring nothing except adding a scope.
