Chuck, Bob tried, but unfortunately he couldn't help. There is not enough meat on the barrels to open up the chokes and correct the POI.
Do you think Briley's could help? I talked with a lady(technical support) from Briley's who said that they can put in thin eccentric chokes. They needed only the barrel and my POI trial. What amazed me is that she said they don't even need to shoot the barrels as they can calculate exactly how much to correct the POI from my info then cut this into the barrels.I am not confident that the lady knew what this job would take, although it sounded like she did.
