This is a prairie dog gun, with a little over 4000 rounds through it. I don't have a bore scope but see no reason that the rifling would be bad. It also gets re-crowned periodically. Accuracy has just fallen off to where it no longer shoots well enough for pd's. I will of course have it checked out before any thing is done. I believe the throat s gone. Just wondering if a set back would be worth the money or not. KN
