DoubleD look at the bore to choke transition with the flush choke snugly threaded I’m guessing it won’t be a smooth transition like with the Brileys ; Hence the donut blown pattern.

What shotgun is it ?
Bailey chokes are top tier, but not always perfect. I got a set once that needed the threads cleaned up
