I picked up what I think is a Breda M1 Garand today. No plans to buy it. Popped in a little country store that sold guns, and it came home with me. Still in the heavy grease from storage. Where do I look to find out if it's 7.62x51 or 30-06? I know very little about Garands. Just stumbled upon this one. Can't find a calibre stamp.
