I just saw this thread. Turns out I have three cartons of WLR primers of three different lots. I did not have any idea when I bought them. I had used 100 from one of the three cartons.

I called Sharon this morning and she called back a few hours later. They are sending me proper shipping materials and a shipping label. They will send me three thousand replacement primers.

FYI the lot numbers are
YLL274G
HDL527G
GGL307G
