A friend inherited a nosler ncr 300wsm. Has the original leupold vx3 2-8 and aluminum gun case that it came in. He wants to trade it for a dirtbike i have but im having a hard time finding a good current fair value as I told him I'd probably just sell it myself. Google search has only shown me 2 that listed a price but no date to know if they were recent sales or not. Anyone have any idea of a fair current value?
