I theoretically you could get a barrel ring bulge. I'd tend to start with IC, pattern it, then work up to modified. If steel patterns OK with mod, I'd leave it at that. It's possible the new chokes are labeled for steel, unlike the older ones which were labeled for lead.
I have a older Win 101, the first ones they ever built with the all new Winchoke back then (1980) Even with IC and mod it shoots really tight with steel, so I mainly use skeet and IC for all steel from #3to BBB.
It would always kill reliably if the nut behind the stock weren't so loose!
