For those "tuning" their Accutrigger to a low release weight, test with a trigger pull gauge (or a calibrated finger) with the blade spring installed AND with the blade spring removed. Remove a turn or so from the bottom of the blade spring, dropping it to about 3oz of pull and the difference might surprise you. Pulling on the blade also pushes on the trigger.
I think about 50% of total pull for the blade is a good spot (just a guess).
When you get the pull where you want it touch the SIDE of the trigger and see if the side slop trips the trigger. Guess/measure the clearance between the trigger and hanger and shim up CLOSE to that. Probably 0.015" to 0.020".
Side movement twists the trigger resting on the sear and can cause a ND. Test with action out of the stock, AND with the rifle all put together and the action screws tight. Some test with a stock bump and by slamming the bolt home for trigger drops.
I still have the standard trigger/sear in the wife's rifle, just changed to a lighter target spring and cut the blade spring. At about 7oz total I feel I could make it a little less but the wife likes where it's at. Maybe when she gets better with position, repeatability, stress of competition, etc., I'll go lower.
Will it EVER get to 2oz? Nope, never happening.
