Recently took this in on a trade and was wondering if anyone knows anything about it. It's pretty clean, few hunting marks, normal wear on wood and metal. It's marked "Magnum" on the receiver and says it takes 2 3/4 or 3" magnum on the barrel. I was told it was an early 80's gun. It has a 28" fixed full choke barrel. I was wondering how it would be for an all around bird gun from doves to ducks. Can steel shot be fired thru it? What is it worth roughly? I would rather have one of the Rem choked barrels but I don't know if they are interchangable with this model or not. A smith has told me that he will chop it to 26" and tap it for Tru-Chokes for about $80, good idea?
