I am another one of the cretins shooting non-dominant eye. Fair to middling with a Rifle. Used to SUCK with a shotgun. Before I found out about cast on, proper fit, comb height, LOP, etc... Have learned that there is a lot that goes into proper shotgunning. And have tried to adjust accordingly. Still not "competitive". But definitely better than when I started.

One learning is "Don't assume" that a "Left Hand" shotgun is set up for a Left Hand shooter. Had a LH Benelli SBE for 2 or 3 years before I found out that the stock shim plate for cast had been set up for "Cast Off" for a RH shooter... frown
