Thats hard to tell. You need a detailed description of the rifle, overall condition, rounds down the tube, and photos if you're comfortable with that. The going rate on Gun broker is anywhere from $650 - 1000 for the model you described. Brand new on rugers website they are going for $909. I hope that helps. Good luck!
That is what I was looking for. A few years back I had 27 rifles stolen, this was one of them (got 4 back) and not having the funds to replace them I pretty much keep everything I have. I sold a 220 swift on here and that was tough decision. I loved that little rifle.
It has around 500 rounds through it and is in good shape. I will snap some photos.
