One cause of the problem can be the inletting in the trigger area is too tight, putting sideways pressure where it should not be. A few thousandths relief fixes that - as long as it doesn't re-occur.
I built a new stock for my 700, once upon a time, 40 odd years ago.... still has the same Walker in it, working fine.... since. And no, there was no AD, since there was no round in the chamber on testing for function.
I have often wondered if the above observation isn't responsible in some factory stocks as well.
