I have an original factory barreled Ruger MK II long action rifle without sights, with both the wood stock and a Ruger skeletonized synthetic stock chambered in .375 Whelen Ackley Improved. Rifle was made in 1995 and is in super condition. What would be the value of such a rifle. I know that the new .375 Ruger has eclipsed the .375 Whelen AI in power, but this rifle is one of a kind and a great shooter. Any ideas of worth? ;D
