I usually go by the market value and NOT the book value. In other words - Go to
www.auctionarms.com and search closed auctions for the model/caliber of gun/rifle that you have and see what others are paying for them. You can also search ongoing auctions to get a rough idea. Something is only worth what someone is actually willing to pay for it.
My analysis tells me that if your Rifle/Shotgun combo is in fine condition - it is worth roughly $450 without a scope. I always sell my rifles WITHOUT a scope and sell the scope separately.
