I am considering buying this gun and would like to know what a fair price to pay would be? It is a custom Remington 700 with extended bolt handle/knob, HS Precision stock, Shilen #4 fluted barrel (stainless match grade) in .257 wby mag, jewell trigger. They are asking around $900 for it. The barrel has 15 shots on it and he will guarantee it to shoot sub .5 moa @ 100 yards. It was built by a quality gunsmith locally and is in excellent condition. The action has been used on another gun, everything else is new. What would be a good price for this gun? I am going to reload so Im not concerned with .257 wby ammo prices. This will be used for whitetails, hogs, and a few coyotes here and there. Any reason why I shouldn't buy a .257?
