All the Tikka and Sako triggers I've ever adjusted stopped at 2 lbs.
The reason that the trigger pull On the Tikka T3 cant be adjusted lower is that the head of the trigger adjustment screw contacts the bolt that holds the trigger to the action.
Take the bolt out that holds the trigger to the action and take the trigger off and file down the head of the trigger adjustment screw and that will allow the screw to back out farther before it touches the Bolt.
That will allow for a lighter pull.
This is for the Tikka T3
