There won't be much of a reduction of blowback with different bolts. The amount that you get is, I believe, mostly a function of how quickly the hammer/bolt assembly moves back. More airflow to the striker with a lighter spring means that the bolt will blow back earlier causing gas to be wasted during the shot. The ideal ratio is to get just enough gas to the striker to blow it back while having easier airflow to the barrel. This gives the ball a longer period to accelerate before the breach opens up, wasting air.
