I followed the advice here and used the 10-24 screw and lighter spring on the trigger. I also used brass shims to remove all the wiggle and play from the trigger. Cleaned the sear and notch and used a high end grease. Went from 5 1/2 to 6# pull to right at 3 1/2 lbs. Trigger has slight creep but has zero over travel since setting the cap screw. I don't like super light triggers, so 3.5 # with a slight bit of creep is just fine for me. Next up reinforcing the stock with steel rods and epoxy.
