Long Path. When I worked for a gunsmith, many years back now, one of the things I learned from him is torqueing down screws in aluminum. Tighten them down, a little at a time, going back and forth. Wait a couple of hours, and you could get a few more fractions of a turn out of them. I'm pretty sure the screws were properly tightened. I have another 30-30 with a 5D sight on it that I have not shot in several years. If I think about it, I'll dig it out and see where it shoots.
