Action flex... what happens?

[obx22]

Probably a dumbo question, but here goes:
If the action has a "puzzle piece" fit to the inletting, yet is bowed or flexed when torqued down, why does it not shoot accurately? I'm being serious, assuming the actions not shifting in the inletting, what actually, mechanically, causes the inaccuracy?
Is it that the stressed metal changes, inconsistantly, the way the barrel vibrates?
Take care,

"Is it that the stressed metal changes, inconsistantly, the way the barrel vibrates?"

Yep, probably the way that the whole rifle vibrates. Also if the action is torqued, the head space at the rim will be a few thousands different than the way it was originally. I.E.: slightly wopperjawed horizontally and/or vertically

If the rifle was built properly, everything was in a straight line - & it should be kept that way.
