Anyone that has moved POI with stock adjustments...I need a sanity check.

My brother-in-law has a sxs Sarasqueta 20g that has a fair amount of cast off. The right barrel hits way left for him. The left barrel is about spot on.

If I bend the stock to the left, toward 0 cast, will the right barrel tend to shoot more to the right?

Speculators are welcome, but I'd sure like to hear from someone that has done it too.
