Greetings All,
A better way to date Dupont IMR powders.
My old can of IMR4064 is marked:
P79SE27B
I believe this means the powder was packed on 27 September 1979 by shift B. This was also repeated by a post on the Castboolit site. My can of IMR4227, with the older label, is marked P77 so packed 1977.
Every day you learn something new is a good day.
Regards Grandpamac.
