Tikka's are great rifles, but I wouldnt put to much stock in what the Canadian Rangers use or their testing. If you lived here you would know why.
In any event their first choice wasnt the Tikka, it was the Ruger Gunsite scout, but they couldnt get them at the price they wanted so went with the Tikka, and got soaked. A good friend did some research and wrote an article on it and if my memory is correct they paid over 3k per rifle.

I have Tikka's, and they are fine guns, but as far as reliability goes, the Winchester/ Ruger wins hands down.
