I have a supposed dummy round found among my friend Greg’s stuff after he died. He wasn’t a collector or a reloader but he was a bit of a squirrel.
The round is apparantly 7.92 and has on the headstamp n’n except that the ’ is actually a small 7 and the second n has a curved right leg. No problem so far. That headstamp is (I think) from the former Yugoslavia, possiby Croatia I believe and I have seen it before.
The headstamp also has 5-56 and SS and thats where I have a problem. The 5-56 could mean May 56 but I wouldn’t have guessed at it being that old, I may be wrong. I am surprised they would include the month on ammunition from this part of the world. Obviously it has nothing to do with 5.56mm
The SS I am at a loss with although I am aware of the significance of S on German ammunition.
There are a couple of other small puzzles. It has a silver fired primer which looks non standard but there is absolutely no flattening of the primer what so ever which you would expect from a round of this pressure.
It looks like a reload but there is no hint of a resizer line and there is no slight ring around the case just ahead of the extractor groove where the chamber finishes. The next though is that its a misfire and it might well be but it doesn’t give off any noise when shaken.
Any help would be appreciated, I cannot post a picture but if this thread gets tricky I could possibly arrange for someone else to do it for me.
