$150-$450 depending on condition and features. If it looks as if it came out of the box (I.e. no safe dings, no blemishes, now marks of any sort) and has choke tubes it might go for the higher amount to the correct buyer. If it is a fixed choke then expect less, especially if a Full choke.
These guns tend to not cycle 2 3/4" target loads reliably as they are not ported correctly for them which makes the gun less versatile. Shooting heavy field or magnum loads can get spends in a short time. The best part is the 2 3/4" chambered LW barrels fit on the Magnum receiver and then the gun will work reliably with lighter loads. Just make sure it is an LW barrel and not one of the other versions Remington put out over the years as they wont fit.
