Before I determined that I had a problem, I would use the BSS first with the ammunition I use on pheasants. At the minimum pattern the gun.
Have you actually measured the constrictions with a professional bore gauge to determine actual choke? Not the brass things that you stick in the bore.
After I had done those things, I would make a decision.
And then If I determined that the chokes were too tight, I would not install tubes but only change to IC/Mod.-Dick
