Location: It is the tradition that a Kentuckian never runs. He does not have to. (1931)
I have nowhere learned how to decipher the lot number on a box of Remington shot shells. I do know the well-known method to decode Winchester lot numbers to learn the date of manufacture.

I wish to know the dates of manufacture of two red white and blue boxes of Remington All American Trap Loads made circa 1970-1972, with lot numbers A S 27 P 9 and A T 19 R 10. Perhaps 9=September and perhaps 10=October. Perhaps 27 and 19 are the days of the corresponding months. Even if that is correct, I still do not know how to extract the year. Would anyone care to help so that I can resolve a current thread on the General Forum? Thank you very much!

The lot number of the pre - All American trap Loads, circa 1964 - 1967, is B C 10 H 10.

The lot number of the All American Trap Loads, circa 1971-1972, is A S 27 P 9.

The lot number of another box of All American trap Loads, circa 1971-1972, is A T 19 R 10.

It is evident that the Remington lot numbering system was unchanged from 1964 - 1972. Any leads for me?

Thank you, pump shooter.

IAA (International Ammunition Association) wrote:
Codes from 1928 and later
Beginning in 1928 the Year code was changed to a “Half Year” code where the letter represented either the first half of the year or the second half of the year. Sometime after 1928 the month code was changed to a 6-digit code word that changed every 6 months so the month codes cannot be decoded after 1928. The format for the code reverted to L##L with the form Year (half)-Day-Month.
Example:
A08A2205252 The date code would be A08A or 8th day of some month in the first half of 1930.
• A is year code: 1930
• 08 is the day of the month
• A is the month code which may mean January.
Data from 1968 to 1978 indicates that the code changed during this timeframe. D’Artagnan on the IAA Forum has a confirmed date from 1978 with codes L and M, and I have a box where the cartridges are dated 1968 on the headstamp. Working between these two dates and assuming the restart of the code began with A indicates that Remington dropped the remainder of the old code at the end of 1972 and started with the new code in 1973. This assumption means dating the codes in 1973 are uncertain since they could have completed the use of the old codes in 1973 and started the new codes with C in 1974. The result is the 1973 codes could be A & B or Y & Z. The list below reflects this.

Year • Year Code 1st Half • Year Code 2nd Half (as partially extracted from the article)
1960 • T • U
1961 • W • X
1962 • Y • Z
1963 • A • B
1964 • C • D
1965 • E • F
1966 • G • H
1967 • J • K
1968 • L • M
1969 • N • P
1970 • R • S
1971 • T • U
1972 • W • X
1973 • A or Y • B or Z
1974 • C • D

Mr. Dick Fraser suggested that the first letter is either the first half or the second half of a particular year of manufacture, and I tend to agree. First we can test the other letters in our three codes and observe that they are somewhat inconsistent with the years that their boxes appeared in the Remington catalogs.

For example, examining only the letters in the second places, C=1964 ?, S=1970 ?, T=1971 ?, we observe that C is possible but S and T are unlikely. Again, examining only the letters in the fourth places, H=1966 ?, P=1969 ?, and R=1970 ?, we observe that H is possible but P and R are unlikely.

But we observe that the letters in the first places, B=1963, A=1973, A=1973 are very consistent with the years that their boxes appeared in the Remington catalogs and the printing of the the wad RPA 12 on the two All American boxes. Earlier I stated that dating manufacture by matching with the years that the boxes appeared in the catalogs was "relatively precise" because production lines cannot be aligned precisely with catalog years.

If this reasoning is correct, then the pre - All American Trap Loads with lot # B C 10 H 10 would have been manufactured in the second half of 1963, consistent with the box design appearing in the 1964 - 1967 catalogs. The All American Trap Loads with lot # A S 27 P 9 would have been manufactured in the first half of 1973, consistent with the box design appearing in the 1968 - 1971 catalogs. The All American Trap Loads owned by wrfish with lot # A T 19 R 10 would have been manufactured in the first half of 1973, consistent with the box design appearing in the 1968 - 1971 catalogs.

The introductory discussion of this dating is A friend gave me some old 12 ga shells. Thanks, everyone!

If anyone wonders why the production date was disguised in the Western, Winchester, and Winchester-Western lot numbers, it was so ammunition would not sit unbought on shelves because people thought was too old.

As it turns out Remington was even more determined than Winchester-Western to prevent customers from reading their lot numbers. Ever.

Interesting! Now I can try to unravel the dates on some of my paper hull 20's and 16's.

Paper hulls. Historic! Try using the first letter for the first half or the second half of the year of manufacture. Post some pictures of your boxes with their lot numbers and I will match them with the catalogs, o.k.?
