I have a wounded soldier out helping me guide a military widow hog hunt. He brought out his brand new rem 700 7mag. He told me the gun would not extract a spent case without the safety on. I know the safety has nothing to do with the extractor ring. The extractor is the rivet type I think and it has no springiness to it. It is just hard against the interior side of the bolt. The bolt has a damaged area on the outside just behind where the rivet is and has raised the metal on the face of bolt ring in the one side. Anyone have any ideas and how would I go about removing the extractor? I have replaced the extractors on the non rivet type before but not sure how to deal with rivet. Disregard corn dog grease on the plate.
