Interesting, looks like it was either dropped or someone attempted to put a cartridge in the chamber then close the bolt. Most likely dropped though. If it was me I would just clean it up with either a lathe or very carefully with a die grinder and some emery. Thats only if it was causing a actual issue. If the firearm still chambers (from the mannlicher clip as its designed to do), extracts, and ejects properly I wouldn’t even touch it.
