If it was worth anything extra, it would be unfired. I'm not sure that it is. Maybe when the Tricentennial rolls around. I might keep it if I planned on passing it along in the family. If I were to run ammo through it, I'd trade up to a newer model that is more accurate. I picked up a target version that I like to switch off to, and it's a whole lot more accurate, plus I think you may have a parts issue with your rifle.
