Any rifle will shoot better with a good trigger. That being said the Accutrigger breaks cleanly and is nice shooting. However, I picked up a Tikka at the gun shop last night. The first one I ever had in my hand. As Retaks says, the trigger is excellent. And the Bolt is very slick. The only thing I saw on it that I don't like is the polymer magazine. I know its tough stuff I have a couple pistols made with it. But on a rifle magazine it feels out of place. Even so, I don't think it will be a deterent in buying one.
And Since Savage came out with the accutrigger, other companies like Ruger and Remington have followed suit - improving or redesigning their triggers. I haven't tried the new Rem or Ruger triggers so I can't talk about them.
