I have had a running discussion with some gentlemen on a gun website concerning the single and double “eye” headstamps on some Japanese 7.7x58 rounds. I have three examples:
- one eye, GM ball, brass case, pink neck seal, knurl on bullet at case mouth.
- two eyes, GM ball, brass case, pink neck seal.
- one eye, GM, brass case, black bullet and case base. Ball?
One of the gentlemen has a short-range round with one eye and apparently has seen others, so their conclusion is that the eye marks a reloaded case. Elks posits that the eye marks signify some kind of special or experimental loading. I disagree that they are reloaded cases, but I’m not totally convinced of Elk’s theory.
Any thoughts, info, or other theories?
