My #1Problem with accuracy

So the lesson here is to make sure your screws are tight, which I thought I did. I cleaned, dried and applied blue locktite to this screw and let it dry for over 24 hours per the instructions. When I checked it after 100+ pellets trying to zero in the scope, the screw took SEVEN twists of a screwdriver to tighten. SEVEN... that's how loose it became. I tightened it and shot some more keeping the screwdriver on the bench with me. Checked it and it was tight. Fired some more, quit and went home. Then I checked it in this video..... I'm going to suggest that I did not clean the machine screw properly/enough. I will clean it again, and I will do my best to clean the portion of the action it threads into. I'll let them dry and then I'll coat the ever living crap out of that screw with blue locktite again, and reassemble. Let it dry and we'll go at it again.
