I have in my collection an interesting type of 7.62x39mm packaging from Yugoslavia. API cartridges in the typical 15 round boxes, but two boxes are sealed in a clear plastic bag. The boxes are side-by-side so that the labels are facing the same way. This is factory packaging I’m sure and I beleive that tracer ammunition has been packed this way as well. Is this typical of all Yugo packaging for tracer and API, or is it customer specific, as both types observed have “export” headstamps (“IK” vs. “NK”)?
