As long as the chokes are modified or less, I don't think twice about using it in mine. Started shooting steel in the BSS at least 15 years ago. Never a sign of a problem. I use a softer non-tox in the full-choked barrel though. This past season I used Win. Xpert steel in the right and Classic Doubles Hevi-Shot or Bismuth in the left. Three inchers. Heckuva duck gun, IMO.
