In reality, I think there's a safe max but no real "correct" number. There are all kinds of opinions/methods on getting it right for your gun.

I just completed a build using an Accuracy International Chassis System- and was surprised that their directive was to tighten the action screws to 53 in./lbs.

Not 51, or 54, but 53...

Can't help but wonder how that was determined.

Action screw torque setting have been determined by machine resting the rifle then shooting 20- to 30-shot that's groups at different torques. Whatever makes the smallest groups is the spec. It varies with action types. But for a given action, the amount seems to be the same across all stock materials except steel or aluminum tube guns. I don't know about tube guns.

Most .22 rimfire match rifles do best with 20 to 25 inch pounds.
