I have a weatherby rifle in stainless/synthetic. The trigger seems harder to pull than my Tikka or my sons Sako. The trigger is set @ 3#. I see an adjustment screw by the trigger . . . I imagine that turning it counter-clockwise will reduce the weight needed for the trigger to fire. How many turns would I have to go to reduce the trigger pull to 2 1/2 #? Also, I thought I would check the free floating barrel . . . but could not get a piece of paper between the barrel and the forend. Do I need to sand the forend down so that I can slide a piece of paper thru or is this common with synthetic stocks so no problem. The gun will shoot 1.5" groups (which is what Weatherby guarantees), but I would like it to be at its best w/o messing it up. Any help will be appreciated.
