On the top flap of the box (inside) is printed ”K77DE22TS”. Other than that, no traditional date stamp of any kind. On another forum a member said that he thought they were made early 60’s just from the style of the box.

July 7th 1955 or 1975. Id say 75.

I'm throwing my guess in the ring, since I have nothing better to do and have no clue. Dec 22, 1977

Me either. I got them from someone who got them from a estate sale. They had no information other than the previous owner was in their 90’s.

I never have been disappointed when shooting a vintage shotshell, the opportunity alone eliminates that happening....plus, I miss with more modern offerings.
I must be too easily satisfied.

I should probably have said that my "guess" was based on the date code you provided. You can cross reference with the Win/Western charts to see the dates, they repeat every 20 years.

Thank you. Where might I find the charts?

The Mark-5 plastic shot collar appears in the 1962 catalog, with the Super-X and Xpert still in paper hulls. The plastic hulls appear in the 1964 catalog, compression formed for the Super-X (like AAs but with higher brass) and poly-formed (plastic tube with a fiber base wad) for the Xpert. Those style boxes were in use through 1972. By 1973 The Western Super-X had moved into the white boxes --

in 1971 the Xpert got replaced with the compression formed Upland --

I assume the number I quoted earlier is just a ammunition production lot number? And nothing to do with a date? Thank you for the information.

The date is in the lot number, but deciphering is a bit complicated, because of repeating cycle of year code.
Probably way more information than you were looking for, but here's a reference

Thank you. Very interesting. Now I’m curious how old other boxes I have are.
