Thanks to all of you who replied to my post. Retriever Believer- the file you sent had more information than I had been able to find in the three months that I had the gun. My next question for you guys with all of your knowledge is--Do you think its feasible to have another set of barrels made for it or even possible. The gun has a few light handling marks on the stock, otherwise in excellent condition. It's choked mod/full, and I would like to have another set with more open chokes for grouse. With the trade I figure I have about $2200.00 into it. Opinions? Thanks.
