I had a guy bring me one once where he’d drilled all the way into the chamber, like a pressure barrel for a copper crusher. His complaint was that ever time he shoots he has to put a new screw in the front base hole because they fly out and hit his scope! And the brass has a hole in it for some reason.
I put a new barrel on it and ran the base screw holes out to 8x40s and had a customer for life.
