As the subject title says, the bolt assembly screw on the back of my Savage 110 bolt likes to unscrew itself after a few rounds. The other day it almost came off.

Based on what I've read they're typically very tight, to the point where they're difficult to remove when needed, so I know this is not normal.

Is this a problem that can be solved with a drop of locktight, or is the problem more serious than I think?

I called Savage customer service, and because my rifle was made before 1995, they won't even talk to me. They won't answer questions, give any advice, or help at all.
