Well, is it a blue barrel, or stainless?
If you pay to have it shipped, I would recrown it for $10 dollars. That includes the refinish work on it after, bluing and what not.
I would also try to see if the chamber was bad or not. Not like that is going to make it string like what your talking, but it could hurt it.
So basically your looking around $20.00 after shipping. I would recommend sending your action with it. Your lock up and fit to the frame could have a little to do with it. There is just so many things that can cause it to not shoot. (if you have other barrels and don't want to send the frame its ok, I don't think that has much to do with it....it just wouldn't hurt to check) You can see if your barrel wobbles on the frame when locked. If not then it should be fine.
From what your saying tho, it sounds like the crown.
