I am unfamiliar with the Abolt II but all triggers have three possible adjustments. Although some only allow you to easily adjust 2 of the 3. The three are - creep - pull weight - over travel. Lightening the pull weight should have no effect on overtravel. Clean the trigger assembly and try again. I looking at the schematic is looks as if the pull adjustment is altering the tension on the trigger return spring. The parts affected are 85-87. The spring is the trigger return. Changing it's tension should not effect the overtravel, which is motion of the trigger after the sear has released. If lowering the pull weight alters the overtravel the fix is to install a lighter spring of the same length.. so that the adjustment spring can be maintained at it's current level.. The alternative is adjust whatever is acting as a stop..
