In eastern Ontario the gun would go for less than five hundred bucks. If you had $500 on the gun at a gun show, it would not even get picked up. The scope does not add much to the value unless it is an Elite or a Japanese manufacture like the older Banners and Trophys.
I agree with the suggestion of $450 as an honest price for both buyer and seller. They are an excellent rifle, and I prefer them to the 7600s, but most gun buyers are younger folks and in many cases are not familiar with older models (think Remington 721 and 722, for example - excellent, indestructible actions, and almost impossible to sell these days....)
