Thanks. I'm just starting to waterfowl hunt and I'm trying to figure what to shoot. I have had plans to make a patterm board, but so far other things keep getting in the way.
It's tough figuring out a choke for it because it's an odd barrel. I bought it in the mid 1990's for shooting clay birds, but went a different direction. (that's the short version)
It's a Stan Baker Big Bore Barrel, basically an overbored (.025") 10 ga barrel but chambered for 12 ga shells. It's used on a 3" Rem 1100. The Mossberg 835 barrel is .775" and this one is .800. Briley wants $75 per choke tube and a month turn around time. Friends have used those shells but said they had inconsistent velocities when used in extremely cold weather.
