Have you tried taking it to a gunshow to do some trading or you might be able to sell your gun at the gun show just by walking arount with a 4 sale sign on it.
I might add that I have seen remington bdl 7mm mags for under $500 at gun shows. If you end up getting a ruger, don' t buy the one that has the flimsy sythetic stock, it' s a very inaccurate gun with that stock.
