Good afternoon,

Just a general question for somebody that is familiar with the PMP lot number system.

I recently bought a crate of 1260-off PMP 308 Win rounds. These are packed 20 per box and 7 boxes per sealed plastic sleeve. The lot number on the lable is LOT 052D21. Does anybody know what this means in terms of production date etc. The headstamps are all PMP 308 WIN and not D as seen on recent 223 lots. Assuming it cannot be 2021 vintage?

Thanks in advance for any feedback provided.
