Thank you very much for your suggestions.
I happened to find out that Montana Long Guns is almost my neighbor. I will visit Tom next Friday and shoot the gun for POI with him, then see what options there are. He sounded very knowlegeable and reassuring on the phone.
Chuck, I think your idea is very good. It might be the only thing to do as the barrels are not very thick and existent chokes quite open.
ChiefShotguns, info like the one you provided is what I need. I would have sent the barrels to Briley's as next step.
Eventually I will see what Tom at MontanaLG suggests.
Thanks again,
Justin
