[QUOTE="dennishoddy, post: 2519720, member: 5412"] The stainless steel that gun barrels are made from are magnetic. They have multiple alloys in the barrel that make them so. The stainless that is not magnetic is too soft. I've witnessed hundreds of MPI inspections in the company I used to work for. The tiniest crack can be detected. It may need some magnification, but the shops that perform that service have what it needs. [/QUOTE]
