If I were you. I would set the trigger a little heavier than that. I had a Savage 12 in 223 that came from the factory. Single shot 26" bull barrel. First live round in the chamber, close the bolt and bang! Next three did the same thing, and even when closing the bolt, safety on, it fired as soon as safety released. Adjusted it to about 1.0 lbs (Target ONLY rifle) and problem gone.

My hunting rifles all run right at 2 lbs. That is plenty light.
