I shot an SKB 100 12ga 26" IC&MOD with steel from the 70's until I started to phase out all my single trigger shotguns. It worked great.
I switched to two trigger doubles and most of mine were older and shot ITX shot for all my non-toxic stuff. I ran into a range that had gone to non-toxic and started to also shoot some places that I was going to be in the higher volume shooting non-toxics, doves, snipe and coots. So I did the same thing picked up a CZ Bobwhite 20ga.
The CZ Bobwhite is a nice little shotgun, mine is a 26" 20ga. I'm short in stature so the stock got cut an inch and is a nice handling little shotgun. It kills clay birds and doves well with Win steel target 7's and coots and teal with Kent upland steel 5's, I buy both of these by the case.
I suspect that just about any stoutly built sxs with the chokes opened to Modified or less should work fine. I say stoutly built as there aren't any mild factory steel loads.
