Probably need to get it evaluated by a riflesmith. He'll be able to bore scope the barrel, check the bedding for binds and such stuff as that.
What kind of ammo has he tried through it? Factory or reloads? what weight bullets? Ton of questions and things he can try.
I'm not a Springfield kinda guy but it's a rifle still. Let us know. JohnnyK.
