Is there anyway to tell the age of your primers?

[pittsbirds]

Hello, I am new to the forum. I was just looking at some CCI primer sleeves and noticed some numbers/letters pressed into the cardboard on each individual sleeve. I have no idea what the age of the primers are and would like to FIFO ( first in first out) them. My question is are those numbers/letters pressed into the cardboard a way to date them?

Those are probably lot numbers and I imagine you'd need to contact CCI to learn more. Good luck, and keep us posted!

Also, welcome to THR!

Are the sleeves green and white? If not don’t worry about it. Even green and white CCI primers from the 60s-70s are still good if stored properly IME.
