I wouldn't shoot steel shot in a full choke. Even if the barrel is steel-proofed, a full choke would at the very least destroy the pattern with steel shot. I have not read any manufacturer that recommends steel shot through a full choke. Some say no tighter than Modified, some only recommend cyl/IC. Maybe someone else can shed more light.
I hope I'm not out of line posting something I found on another forum but it provides some more information, even though second or third-hand and related to current production H&R/NEF guns:
I posed this very question to Customer service.

Yes you can. Extensive use can open your choke up a little but it is not dangerous

Subject: Pardner Shotgun question
I recently purchased a 12 Ga. Pardner with a 32" full choke barrel.
The S.N. starts with NM. Can I safely shoot steel shot thru this gun?
