I toss the screws in a little container with a splash of acetone. Shake and bake for a few seconds, then fresh loctite and back in. I don’t think they need to be pristine to hold.AND bore sighting. I don't want to remove the action because then I have to clean the friggin loctite off the action screws, which takes forever, then reloctite it and also verify my zero again after reinstalling the action. They're legitimate reasons.
