RE: Tikka or Ruger M77
I have owned Rugers in various calibers and I have owned two Tikka White Tail Hunters with composite stocks. If one of your primary desires is to have great accuracy, out of the box, the Tikka White Tail model or higher, is the way to go. I do not like the T3, as I believe that Tikka sacrificed too much in quality to get the price down.
If money is no object, the SAKO can't be beat for accuracy and reliability.
