I haven't duck hunted in 20+ yrs. I plan on going in a couple of weeks and might only be for one hunt this yr. My question-the only shotgun I have is an old (over 30 yrs. old) Rem. 1100. Is it OK to shoot steel shot in it? Or would it be OK as long as I don't shoot too many through it? It is a full choke. May be a stupid question but I have heard both ways. Thanks, Eddie
