I have two Savage B 25s, one in 22 Hornet purchased about 7 years ago and one in 17 Hornet purchased last week. Both rifles have a slight burr around the bore on the crown which you can feel with a fingernail, and also see with a magnifying glass. Has anyone else come across this? None of my other Savages have this. Even my cheap B-Mag crown seems to be perfect, according to a gunsmith. (Btw, my B-mag purchased last summer seems to shoot about 1.25 to 1.5" at 100 yards with Win. ammo. Did a little work on it and will try it again, soon, I hope.)
